Everything Oga BigRovar has said just reinforces my conviction that flooded batteries are not suitable for solar RE applications or if they are to be used, one has to plan his charge and discharge and battery bank size very carefully. The goal of every solar power user I have ever met is to squeeze out every last ounce of juice from his PV panels to satisfy the demands of his loads and push maximum amount of power into his batteries within the limited time frame of 1 solar charging day. At some point in my journey with flooded batteries I throttled my charging output to 45amps when my PV panels could put out 75amps - this worked until there was no one at home to use any appliances for a while and then most of the amps would still make it to my batteries and boil them - I was not ready to be adjusting my CC amps limit on a regular basis and it made even less sense to me to just put on equipment loads I did not need just to take up the excess solar power. I remember when I kept complaining about my batteries boiling my Madam advised to leave one AC permanently on in the house and I said a point blank NO. Give me a good Lithium or AGM or GEL any day and they will take a charge rate at 20 to 35% of their AH capacity without breaking a sweat. Heck I hear you can even charge Lithium from nearly empty to full within 1 or 2 hours. earthrealm: bigrovar: 2 Likes |

Re: Solar Energy, A Complement To FTA by sharks776(m): 9:19pm On Feb 18, 2018 |
Hello, I NEED SOME URGENT ADVICE PLEASE. I have a 1.5kva 24v inverter (safe power, problem free 3yrs and counting ) with two quanta 12v 200ah batteries I use. I also have a 6pcs of PV 130w each in 2x3 with a 40a 24v must solar mppt charge controller. The issue is my batteries are weak (3yrs 2months), they don't last longer than 4hrs with just a ceiling fan on at night or day. Sometime s we go 2-3days without light in my area .So am thinking of getting a hybrid inverter of either 2kva or 3kva, so at least I can still light straight from the PV's during the day before I can finally change the batteries. I hope its a good idea and what type of hybrid inverter will be best? |
Re: Solar Energy, A Complement To FTA by makavele: 10:16pm On Feb 18, 2018 |
^^ Those batteries don try . . considering the fact they must have been abused due to under-charging . . . 3yrs + abuse no be beans !!! |

NiyiOmoIyunade:Gel is actually worse than FLA. gel batteries will take an average of 4hrs of bulk charging @ 0.1C rate to reach about 75 - 80% SOC. At least most gel batteries. I have seen some gel claiming to have similar charge profiles as AGM. However AGM is still the best for getting the most from your PV. 1 Like |

NiyiOmoIyunade: You can charge Lithium Titanate Oxide (LTO) batteries at 8C (800% of its rated AH capacity). The Toshiba SCIB cells that I have can be charged from 0-90% in 10minutes if have the required amperage. 1 Like |

chris81964: Can you please elaborate more on batteries shutting down at 32 DEG. ( I heard it in the video) MY BYD batteries are happily offering full rated capacity( design discharge current limit of 0.7C even at 40 DEG) But I remember one of the Victron dealers suggesting that they do not bring in Victron Lithium as Nigeria temperatures are too high for them My temp of the inverter room regularly hits 40 DEG Attached below is the graph of the temp monitor placed outside the BYD box. My cabinet is not even force cooled so the bank will be at higher temperatures. I have attached photos of inside and the manufacturer's photo of the cabinet ( too late to snap a photo) 1 Like

My surprise is not just about my tripping breakers alone as you all are right about breaker undersized capacity. Intact the first thing too on my mind was solar flares. Wikipedia to the rescue. My main issue is that my CC is rated as 3KW, 60A mppt CC. At 581w I am already having 42Amps. What's gonna happen at the 3kw mark? |

Hello house, I hope you all had a great week  ! We recently came across a client who abhors mounting solar panels on his steep slope duplex roof . we had to improvise solar mount design on the overhead tank base with the help of galvanized pipe and clamp. The client is a 24v system fan & this set up is meant to power lightening points with basic security lights , fans, selected sockets and 80L refrigerator on timer"madam insisted even before inverter upgrade ",and minor loads as client intends upgrading his 2kva inverter system soon. In details , items supplied comprises of ; -Bluegate 2kva 24v inverter "clients old system" -325w(6) mono pv -200a agm(4) batteries -Ep solar 60a mppt -10mm (22m) solar cables , pv connectors, 63a double pole DCB, other installation accessories.

pranil: Hello Pranil, I hope all is well. They restarted at 32 and stopped charging at 40 degrees. The Lynx ION BMS has a lot to do with what happens. Early this morning they full charged with the battery temperature remaining within range. We limited the current to 60 amps as suggested by Victron. The BYD are clearly a better choice than the Victron. They have better thermal management than Victron. The fans run constantly. We will add an AC when we add additional batteries. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 2:19pm On Feb 19, 2018 |
Dam5Reey has said it all. Your CC is rated 60A. Anytime you get a reading in amps the next question you should ask is 'at what voltage?' so that you can put things in perspective. A typical CC capable of handling a 12v/24v/48v battery bank is most efficient at the upper voltage limits. It is only at the upper voltage limits that you can use the full rated power of the Charge Controller. So you see on average for one 60A rated charge controller 3kw to 3.2kw Max PV size for a 48 volts nominal battery bank (60Amps * 54Volts average charging voltage) 1.4kw to 1.8kw Max PV size for a 24 volts nominal battery bank (60Amps * 27Volts average charging voltage) 600Watts to 800Watts Max PV size for a 12volts nominal battery bank (60Amps * 13.5Volts average charging voltage). Power (Watts) is always Amps * Volts so you are being limited because you have setup your system with a 12v nominal battery bank. The same Charge Controller you have now could easily accomodate 3 or 4 times your current solar panels if you switch to a 48v battery bank and inverter. Choosing a 12v system/battery bank is keeping you at the lowest end of the power curve so you can only access max ~600 to 1000watts in a 12v nominal battery bank. You will never put through 3kw of power at 12v unless you upgrade your inverter and battery system to 48v. Ijeoma660: Dam5reey: 1 Like |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 3:07pm On Feb 19, 2018 |
Based on what you have represented below; you already have a charge controller which by all accounts is functioning well and also you have a trouble free inverter. As it appears you are not ready to change your batteries yet, an 'Hybrid Inverter' may not help you at all as it merely combines the solar charge controller and inverter feature in one single box. The Hybrid Inverter still needs batteries to function except it is a grid tie inverter you have in mind and going that route will very likely be more complicated and costly than a simple battery change. Assuming your MustPower charge controller is functioning well, power generated from your PV panels will be directed first towards your loads then any excess power will go to charging the batteries - what I'm trying to say is that what you already have should be achieving your objective unless I am missing something? For your batteries, they have done well to last 3 years especially as 6*130watts panels would not have been enough to charge them properly unless your loads are very low or you are getting PHCN or Gen to complete the charge. Have you checked the battery voltages when your inverter low battery alarm goes off? You may be able to identify a weak battery that may be recovered with a few complete/proper charge cycles. Please revert with further details and we can take things further. sharks776: |

NiyiOmoIyunade: Thanks your response. What I have is a grid tide inverter. The charge controller supplement whenever the Grid is down (I hate generators). Pls see sketch below. the reason I want a hybrid inverter is just so I could get power for my appliances straight from the PV during the day. My multimeter is misbehaving, will get another one tomorrow God willing so I can test the individual batteries.

NiyiOmoIyunade: The brand is Infinitum Hasn't disappointed me in many years. Bought the first and was impressed thus got two more. Recently got 4 more. And yes, short commutes are the natural enemy of any vehicle battery. |
Re: Solar Energy, A Complement To FTA by Oshomo12(m): 8:01pm On Feb 19, 2018 |
sharks776: I want to belief it's not a grid tie (maybe u meant an inverter that uses the grid to charge ur batteries). Grid tie inverter supplies directly to the grid, aka Phcn. Just as @NiyiomoIyunade said, ur batteries are quite strong to have last this long(6 of 130 w panaels can't just cut it! a little small to charge those batteries well). My brother, go and buy new panels before u think of replacing those batteries fa! And No, u don't need hybrid inverter, cos u have one in conjuction with your controller already.

sharks776: Honourable . . A grid-tie inverter supplies electricity back to the grid . . You wan start to dey sell "light" ? I guess not . . You do not need a hybrid inverter . . because you already have a charge controller A hybrid inverter is basically an inverter + charge controller (2 in 1) package . . . Best to get a standalone charge controller, the ones in the hybrid package are of lower specs "pound for pound." You cannot power your appliances straight from your PV as you have put it in your context . . . Your PV supplies DC, the controller supplies DC, so how the heck you're gonna do that . . ? Unless of course you're running DC appliances matching the voltage range the PV and contoller is pushing out. You're running regular loads, you still need an inverter to do the "inverting" Finally, those batteries have really tried ... Like Niyi said, get a multimeter and check for a Judas; but I recommend a complete overhaul . . Not forgetting to add more panels before battery change Else, back to square one. Brah Matiu, do your thing !!! |
Re: Solar Energy, A Complement To FTA by sharks776(m): 8:22pm On Feb 19, 2018 |
Oshomo12: Thanks for the correction, I actually mean my inverter uses grid to charge and the charge controller is also connected to the batteries (charges it when the grid is down). 130watts PV ain't easy to come by around here, can I mix with a different watt e.g 300w. |
Re: Solar Energy, A Complement To FTA by makavele: 8:28pm On Feb 19, 2018 |
sharks776: Brah Matiu, you are not permitted to do so. Do it and you'll essentially have 130 + 130 Watts instead of 300 + 130 Watts lol 1 Like |

makavele: I thought as much. My dilemma is that my power inverter is practically a UPS. I want to use the power from my PV the run some appliances. The charge controller that charges the batteries cannot give me an AC output for my appliances hence the reason for me asking if I can change the power inverter to a hybrid inverter. Below is an exact diagram of my system, the blue dot line is what I desire to have in other to have AC output for my appliances.

Re: Solar Energy, A Complement To FTA by davodyguy: 9:04pm On Feb 19, 2018 |
Hello guys. Urgent need your advice on this 1. I have this 1000 watts invert, 12v 2. Bought two numbers 200amps Gennex batteries since April, 2017 and it was connected in parallel form to keep with the 12v rating of the inverter 3. Today, I decided to do Solar, so I bought 2 numbers 300watts Solar pa Nels and now have 600watts Solar panels 4. The charge controller is 40a E smart Mptt 5. Connection was completed around 6:00pm, so the panel couldn't send a charge. What we noticed is that despite not loading the batteries at all, the icon on the display screen is constantly showing a discharge. I.e signal keeps going to the bulb on the screen showing a discharge sign. Though no clamp meter to check is current is actually flowing out, but this lives me confused as to what's going on. I need advice so I don't regret investing in this. Thanks all

Re: Solar Energy, A Complement To FTA by makavele: 11:31pm On Feb 19, 2018 |
davodyguy: it is not discharging . . . the load mode is turned on . . . these tier 2 charge controllers usually have 2 extra ports where you can connect light DC loads like led bulbs and a small dc fan etc. they are not meant for large loads. . it has different modes.. it could come on automatically at a preset time; go off automatically, enabled or disabled. in my case, it comes on around 10am and goes off around 6pm; because i use it to power a small dc fan which cools the mppt during operation If you don't like seeing the icon, just disable it. 1 Like |
Re: Solar Energy, A Complement To FTA by makavele: 11:32pm On Feb 19, 2018 |
p.s.: you need to double your panels... 600 Watts panels cannot sufficiently charge 400ah battery bank; unless you are discharging to only about 80% each night. |
