Smartwoods: You can do up to 0.5C which translated 0.5*104, that is 52A. Charging the solar, CC or hybrid I set to max 52A. Charging with Grid I only do 0.2C max which is 21A |

earthrealm: I did look at the cables, it happened that a the negative cable which I had celotape but the celotape got weak and water got into it and it was grounding with the panel frame and as soon as I moved the cable away from the panel everything picked up.

RickyM: Even with the annoying extra costs If you calm down and calculate you'd probably discover that the Canadian panels may still be cheaper than fouani's jinko |

Update on my setup. Sometime last month I connected all my AC to the smart load of my inverter, and noticed that the inverter was going off and on repeatedly for like 5x before stabilizing back on. This would happen severely in a day before the sun goes down as I discovered it only happens during the day. As a result I reverted back to the previous connection and disabled the smart load thinking that was my issue, but it still persisted, so I did some reading online and concluded it might be a software bug. I emailed Deye and requested for diagnosis and update which they did by pushing a remote firmware update to the inverter, yet the issue continued (in my mind I was like I spent huge money to buy a faulty batch of an expensive inverter). I sent an update email yesterday to Deye explaining that the issue is not yet resolved (yet to get an update though) after it happened for the 2nd time in the morning (around 11am). At this point I thought it wise to calm down and observe the inverter when next it happens rather than be angry, so I stayed put in front of the inverter and watched it. Few minutes later it happened again this time around I was watching the screen and boom I caught it in the act and it happens to be that the voltages of 2 strings of panels attached to the 2 MPPTs of the inverter exceeded the max 500v of the inverter (string 1 5x Longi 570w panels was pumping 240v+ as at that time while string 2 5x Jinko 625w panels were pushing over 265v both exceeding the 500v max voltage). As I saw that I quickly switched off string 1 breaker and the inverter stabilized instantly which suggests that the input of the 2 MPPTs are somehow connected in series or something like that as one of the MPPTs can take 500v alone but the 2 MPPTs combined together is still 500v. No matter what you do, do not exceed the max voltage of your inverter and take not of the tolerance of the VOC of your panels when connecting your panels to your CC or inverter to avoid stories just in case your inverter or CC is not equipped to handle any form voltage spike above the rated max voltage of the inverter or CC. @Jonescosmos the 500v is for the 2 MPPTs after all 10 Likes |

Dam5reey1:I vividly understood your points but we need to constantly enlighten and pass the knowledge to those who do not have the privilege information that we have. Money is very hard to get now, even the rich men are also feeling the heat. Getting what we pay for should make us happy and honesty is key to business, especially when there is no warranty or the warranty is not possible to execute. Nigerians should not always be taken for granted. I challenged and I want the Chinese aftermarket (grey market) Lifepo4 Cell/Battery Vendors to stop their fraudulent activities. I will keep exposing them here. Some of them are silent readers here. The Grade B stamped on the QR code by EVE is easily removed with a lazer and reprinted Grade A on it. We've seen video evidence of vendors doing this. That's why all of them are selling grade A cells ![]() SINCERE companies like batteryhookup, Sunfunkits, Ezeal etc selling batched and matched grade A cells will email the manufacturer's test report to you free before you ship out your order. YES, diy users won't have much issue on it but what about people that are buying ready to go battery? Most of these people are heavy users..... 1 Like |

I have never had this kind of issues bro. Please note that the MPPTs are not connected in series, rather they are connected in parallel with some internal diodes that prevents each string from back feeding to the other. I have 4 Strings so far are as follows: LATEST DEYE 8KW + 8KW: INVERTER 1 MPPT 1: STRING 1: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) STRING 2: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) INVERTER 2 MPPT 2: STRING 1: 8X625W JINKO SOLAR PANELS (STC 55.70V V x 8 = 445.6V)(NOTC 42.61V V x8 = 340.88V) STRING 2: 10X540W FELICITY SOLAR PANELS (STC 49.55 V x 10 = 495.5V)(NOTC 42.24 V x10 = 422.4V) PREVIOUS DEYE 8KW: MPPT 1: STRING 1: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) STRING 2: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) MPPT 2: STRING 1: 8X625W JINKO SOLAR PANELS (STC 55.70V V x 8 = 445.6V)(NOTC 42.61V V x8 = 340.88V) STRING 2: 10X540W FELICITY SOLAR PANELS (STC 49.55 V x 10 = 495.5V)(NOTC 42.24 V x10 = 422.4V) PREVIOUS DEYE 16kw: MPPT 1: STRING 1: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) STRING 2: 8X600W CANADIAN SOLAR PANELS (STC 41.3 V x 8 = 330.4V)(NOTC 34.9 V x8 = 279.2V) MPPT 2: STRING 1: 8X625W JINKO SOLAR PANELS (STC 55.70V V x 8 = 445.6V)(NOTC 42.61V V x8 = 340.88V) MPPT 3: STRING 2: 10X540W FELICITY SOLAR PANELS (STC 49.55 V x 10 = 495.5V)(NOTC 42.24 V x10 = 422.4V) My systems worked flawlessly on Deye 16KW, Deye 8KW, and Parallel Deye 8KW + 8KW as well as every other installations I have done, even non Deye Inverters. I will post you a picture of my Voltages tomorrow afternoon. I still believe you should investigate further as there might be a problem with your Panel Strings or your connection on the terminals inside the Inverter. I have seen cases were people misinterpreted the terminals. Please take a good look at the attached pictures. Note that Positive from String 1 and Positive from String 2 are next to each other (Parallel) and Negative From String 1 and Negative from String 2 are next to each other likewise (parallel). The issue you experienced is only possible when you connect Positive and Negative of same string next to each other. EACH MPPT AND STRING HAS IT'S OWN VOC, WHICH IS 500V SO YOU HAVE: 16KW MPPT1 STRING 1 VOC=500V MPPT1 STRING 2 VOC=500V MPPT2 STRING 1 VOC=500V MPPT2 STRING 2 VOC=500V MPPT3 STRING 1 VOC=500V MPPT3 STRING 2 VOC=500V 8KW / 5KW MPPT1 STRING 1 VOC=500V MPPT1 STRING 2 VOC=500V MPPT2 STRING 1 VOC=500V MPPT2 STRING 2 VOC=500V My Most recent project: 50KW MPPT1 STRING 1 VOC=1000V MPPT1 STRING 2 VOC=1000V MPPT2 STRING 1 VOC=1000V MPPT2 STRING 2 VOC=1000V MPPT3 STRING 1 VOC=1000V MPPT3 STRING 2 VOC=1000V MPPT4 STRING 1 VOC=1000V MPPT4 STRING 2 VOC=1000V Ferdiwar: 1 Like

twinskenny: Pray tell. Are these ice block making machines the ones manufactured using Air conditioners? Do they use the flash-freeze mechanism where you can get your ice block ready in less than 24 hours? I have an ice block set up too, but it is with regular 317L freezer and it takes like 3 days for things to freeze over. It's just a means to channel the excess power generated into something worthwhile. |
Re: Solar Energy, A Complement To FTA by isangjohnson: 9:07pm On Jun 09 |
TCD:Jonescosmos has given you the company contact number already. I strongly believe that whoever will receive your call will be someone that has been in the system. Tell them that you want battery pack build with the batched/matched grade A cells with manufacture's test report. I'm sure they have it but the price might be 15 - 20% higher than their usual Grade B battery pack. How to differentiate? Request for EDMS from them and connect the bms to your PC monitor that will enable you to view the charging and discharging of individual cells using the datasheet/recommended C rate. Pay more attention to the upper and the lower knees as I earlier explained in my post. Goodluck |

ojesymsym: Actually I just thought about something now as you mentioned this. One of my tuya devices is a remote control that I use to operate the TV, sound system and decoder from the phone. You can programme almost any remote, and I mean almost any remote, to it and control it on your phone from anywhere in the world. It's just that it doesn't have facility for timer.

RickyM: Techland's canadian 665 watts = 182875 a piece 27 pieces = 182875 x 27 = #4,937,625 Let's assume way billing is #200,000 Crating is #4,480 per 2 panels so for 27 panels there are approximately 14 pairs 4,480 x 14 = #62,720 Total cost for the 27 Canadian panels from Techland = #4,937,625 + #200,000 + #62,720 = #5,200,345 625w Jinko panel from fouani is #184,800 This means I'm buying 1 Jinko watt at 184800/625 = #295.68kobo But for the Canadian panels the total watts I got is 665w x 27pieces = 17955 watts and you recall I spent #5,200,345 total to get them This means I'm getting 1 Canadian watt at 5200345/17955 = #289.63kobo Canadian panels is saving me #295.68 - #289.63 = #6.05 per watt If I must get the exact same wattage from fouani's Jinko I'll be spending #295.68 per watt x 17955watts = #5,308,934.40 But I got same watts at Canadian for #5,200,345 which means Canada saved me #5,308,934.40 - #5,200,345 = #108,589.40 despite the additional crating and shipping fees. So you see... Even with fouani's free shipping, Canada still stands tall Nothing is actually free even in Freetown ![]() 12 Likes |

Good evening guys. I need a battery and inverter to just power my laptop(macbook pro with 45watts charger) and phone, nothing more. The power here is pretty decent just that I need backup power to be able to keep working on my laptop during Nepa downtime and on the days they move mad for example this recent strike. what battery and inverter specifications would serve well for my needs. Also can I go for a lead-acid deep cycle battery since I don't have much power needs. |

Re: Solar Energy, A Complement To FTA by mank1234(m): 11:26pm On Jun 09 |
Ferdiwar: This is invalid diagnosis. All 5kw upwards have at least 2 independent trackers. Both mppt are independent of each other. Check your error log. My suspicion is; One of your string especially, the 625w may be exceeding 17A Isc during tracking. Very likely when sun comes up after cloud on a rainy day. I use same panel but luckily for me my roof is steep. My inverter clips the input current to 13A Imp. If it wasn't steep I'm sure I would be running into same issues. The model you have has 13A as Mac input with caveat not to exceed 17A Isc. Your panel is exceeding that limit that's why it happens. I'll suggest you change panel to panels with lesser Isc else the inverter would spoil in the long run. Ideal for that model is Longi 450W with Isc less than 14A |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 12:05am On Jun 10 |
Icolosis: Buy a 500w inverter sachets ones, since your continuous load is lower than 100w. Get a charger, If the inverter does not have one, get lead acid since you are already thinking about it. My Standard recommendations are: 12V 1KVA Hybrid Inverter with Inbuilt MPPT 40A. 12v 100ah LFP Batteries, cables to connect and you are fine. |
