bigrovar: I've been a fan of your dashboard for several months from last year already, actually; it's so functional and pretty and was partly where I got my inspiration, so thanks. My post was geared more towards novices to visualization resources such as yours truly. Quashie proprietory visualization and data logging interfaces come with my current budget and so far robust components by MPP Solar. I had also during last year tried my hands on building dashboards based on Grafana/Chronograf and the like for use with the PCM60x (attached,) but later slacked off so I'm learning. Now my mind is further energized as I delve further into the Pi 3 ... That being said, I'd still love to build something similar to your dashboard if you'll please share your processes/code with me? My new frontline PIP5048 is also Axpert/Voltronic based, although I'm yet to fully deploy it. ........ P34c3 ..... ...

Greetings my gurus, am a newbie. Pls I have a question. I have the following. Must EP3000PRO 24V, One-solar 60a MPPT, 6 Pieces Poly Panels of 250w each. My question is this if I install all these with 2 pieces 200ah batteries, wont the grid and the Solar be charging my batteries the same time? My inverter is not hybrid. How do I resolve this issue? |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 4:44pm On Apr 27, 2019 |
duwdu: If I am not mistaken the system you are monitoring is the axpert inverter? which communication media are you using? The supplied usb connection cable? I asked because that cable driver is an issue and I was only able to get it to work by treating it as a hardware input device and the hack was not that easy. How did you do the connection in your case? |

duwdu: I'd like to have something like this for the Midnites too. Sadly, the closest I came was with an Android App (though there's some German Raspberry Pi compiles which seem to work just fine). |
Re: Solar Energy, A Complement To FTA by duwdu: 6:42pm On Apr 28, 2019 |
bigrovar: The component I'm monitoring and have shown is just my PCM60x CC so far and it is a Voltronic/MPPSolar product. It is coupled with a VIL Star-Light Power Inverter. Like I said, I'm yet to deploy my Axpert/Voltronic based PIP5048GK. The com cable supplied with the CC (and also one of the cables that come with the PIP) is ethernet/RJ45-to-RS232. Based on what I learnt from MPP Solar and on other forums (chiefly secondlifestorage - yeah, I once saw one bigrovar post on there, hehehe) I then got a RS232-to-USB converter from Amazon. It has worked like a charm to seamlessly interface the CC with my PC/Pi via USB. I don't have the particular link handy, but the trick is to get one with a Prolific chip. Appropriate Prolific drivers are auto installed on Linux. For Windoze, they're available on Prolific's website. (BTW, I also tried the RJ45-to-USB cable sold for EPSolar/Ever products but that did not work for me.) ........ P34c3 ..... ... |

How can I achieve the scenerio below : Make a device to come on only when instantaneous energy from a solar array reaches 1500W and then goes off when it falls below 500W? 2 Likes |

Re: Solar Energy, A Complement To FTA by Barezzi(m): 10:57am On Apr 29, 2019 |
Can you expatiate on what you tryna do? I'm not sure you can do this, and it's not a good parameter to use for control. You can produce instantaneous power of 1.5Kw, but only 200w reach the batteries. Consider using the battery Voltage or SOC for your control system. mank1234: 2 Likes |

Re: Solar Energy, A Complement To FTA by NairaBaba: 9:10pm On Apr 29, 2019 |
pranil: It can easily be achieved if voltage is use as the signal instead of power. I currently have a system that uses the battery voltage as the signal to active a low/high disconnect monitoring Relay which in turn activate or de-activate contactors. These contactors control selected loads such fridge, ACs, sockets etc 1 Like

Hello Niyi, I was hoping you could help me out as you know a lot about batteries. I want to install a 5kVA solar PV system at home. I have had offers for regular lead acid batteries, tubular batteries and lithium ion batteries (GSL Powerwall). I want to know what you think is a good option for me. Setup wise, I've had the following offers 12 Solar Panels (24V, 250W); 8 batteries (12V, 150A) 20 Solar Panels (24V, 250W); 10 batteries (200Ah)/12 batteries (150Ah) 16 Solar Panels (250W); 8 batteries (220Ah) According to my estimates, the fridges use 450W, the TV 100W, the ACs 1472W, the Fans 375W, the Bulbs 135W and the Laptop 60 W. We are moving house so the plan is to cut down on our energy use. Consequently, I'm hoping to wire the house in such a way that when the inverter is receiving power from the panel or grid, everything can be put on but when the inverter is drawing power from the batteries, only essential power points will be available. I've been reading some of your posts and would really appreciate your input. Thanks NiyiOmoIyunade: |

NairaBaba: Not for Solar production. SOC and voltage is not directly related to solar production in Inverter charger setup. if NEPA is available the inverter will keep the battries charged so Solar is still idling Using SOC to optimize smaller loads like Refrigeration and pumps will not optimally work as the PV production can change every minute and may not match the load profile cycling the battery unnecessarily - ( every unit /KWH from battery will cost you 50 NGN while solar will be producing at 25 to 30 NGN so it makes sense to optimize the battery not solar The only way to fully optimize excess solar production is to monitor incoming power and solar production and use AC coupling in off-grid setup USE Battery, voltage /SOC to run a large load like water heater makes sense if the energy gain is significantly high However, the easiest way to do this is if you have a charge controller with load output - e.g. epsolar/morningstar/victron - The load output can start a relay which will control opportunistic loads such a water pumping / AC/water heating - https://www.youtube.com/watch?v=vvNk-VBbCRU see the clip I made earlier where the system only takes 100 watt from grid and balance from solar 2 Likes |

Good day Sir and many thanks for the A2A. When I add all your loads together, I get 1.12kw without ACs while with one AC as you stated we are looking at 2.6kw of loads. With any lead acid battery bank you are looking at at least 20-24 units of 12v 200Ah batteries to power 2.6kw of loads continuously except AC use is planned for solar hours or On-Grid only. With 1.12kw of loads we are looking at 10-12 12v 200Ah batteries to power the load continuously. With a Lithium bank, you may be able to get away with 80% DoD and a smaller battery bank size albeit at a steep entry cost. For 1.12Kw of loads, 12pcs of 250w panels should do, although I always like to oversize my PV array slightly, 2.6kw of loads we are looking at the 18-24 panel option (assuming 48v nominal inverter and batteries). I can't tell which is Lithium or Lead Acid in your 3 battery options but all the battery sizes appear rather undersized for the loads you want to power except you scale down the loads or actively manage them. Long and short is none of the offers seem to cut it at first glance, you would probably have to mix and match across the offers. For panels, I recommend Canadian Solar for solid performance at a good price - You may reach out directly to discuss how you may optimize your system design and I can also supply you Canadian Solar panels and Quanta batteries at very good prices if you wish.

I broke down and joined the LG AC Revolution. I run it from 1030 am to 430 pm daily and for 1 hour at night. I am not so sure that it is that much more efficient than a regular AC. There are many options on how I can run it relative to the window unit I have in my office. My Nissan leaf batteries are kicking ass. 1 Like

earthrealm: In fact, right now there is hardly any electronics purchase I do without taking my wattmeter along. The merchants always look like "what is this guy doing" whenever I request their indulgence to plug in the appliance thru the meter when testing. Apparently majority of them do not know that "energy savers" should be the watchword either on grid power or green power. Oga Ojeysky should get a wattmeter as a handy tool. It'll help a lot. 4 Likes |
Re: Solar Energy, A Complement To FTA by ceaser: 4:06am On May 01, 2019 |
CNN80: I'm assuming your calculation for the bolded are based on the maximum power consumed. So aside from Oga Niyi's recommendation, you can still get more run time if you switch to energy saving mode. Your bulbs can be changed to low power LED bulbs. A 60" Hisense TV that peaks at 150 watts drops to 45 watts at energy saving settings. So you may want to consider using TVs with that feature. |

HI, Thanks so much for answering me. I really appreciate it. I wasn't planning to run any of the heavy power equipment on the batteries although I'm now considering running one AC, maybe one of those inverter ACs. None of the offers was for a Lithium Battery. The 8 batteries offers were tubular batteries; the 10/12 Lead Acid. The Lithium Ion Battery offer was for a SmartLiving PowerWall LiFePO4 Battery Pack (48 V 200Ah/9,600 Wh) with 12 315W Monocrystalline Solar Panels and a 6kVA Hybrid Inverter. I'm looking to conserve power not consume it so the plan is to be as efficient as possible. Which is why I was hoping for an inverter or controller that will send power to the entire house when solar or grid energy is detected and power to a few designated power points when battery energy is detected. What is special about the Quanta battery? What kind is it? Have you used it before? Do you have any recommendations for inverters? NiyiOmoIyunade: |

Hello, How do I switch to enerygy saving mode? The max rating of any of our LED bulbs is 15W and we are planning to change all to at most 10W. Of course we won't have all on at the same time. I am a big proponent of sustainability. By the way, can I run my water pump on solar? ceaser: |

Sure, you can run water pump on solar. CNN80: |
