Penuelseun: My old battery I bought new behaved in similar fashion. No matter how it's charged once charging source is removed, it race down to 12.4V (24.8V for series). Apparently, it was old battery rebranded and sold as new. At C20, I get only 120AH from a 200AH battery before inverter shutdown at 21V cutoff. Two fairly used ones I got from kiekie1 is far better. It charges and maintains 13.2V (26.4V) when full and charging source is removed. 4 Likes |

ojeysky: Thanks bros for that answer, but am corrently using 300w/24v×3 solar panel, what will be the effect since am using 20a 12v/24v solar charge controller. Thanks. |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 6:39pm On Aug 03, 2019 |
durumibaka: From my little DIY experience, It depends on the max VOC of your CC if it's up to 100v or more then I guess you will have your panels in series so amps is maintained but voltage will increase |

Re: Solar Energy, A Complement To FTA by ojtech8291: 8:25pm On Aug 03, 2019 |
ojeysky:I have faced this kind thing before. Assuming he combines them in series and VOC of the cc is 100v but the inverter input voltage is 24v. Is it not going to affect the inverter? I will expect he goes for higher cc of 40A or 50A. Thank you. |
Re: Solar Energy, A Complement To FTA by Namzy(m): 10:31pm On Aug 03, 2019 |
ojtech8291:I don't understand. But wait why do people keep using the old format of 'this is a 12v or 24v solar panel?' I think 300w x 3 connected in series will definitely be more than 100 voc, I might be wrong though. My 340w from jinko and Era solar has a voc of about 47v @stc. Meanwhile I think the problem with the 20a charge controller is the max watts power allowed on said controller. I'm sure it'll be less than 900w 2 Likes |
Re: Solar Energy, A Complement To FTA by mank1234(m): 11:49pm On Aug 03, 2019 |
Namzy: Not necessarily. The wattage of a panel is dependent on current and voltage which jn turn depends on arrangement of the cells (number of cells in parallel and series) and cell characteristics. So for same 340W, you may get btw 30 to 50VoC or even more depending on the manufacturer. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 6:17am On Aug 04, 2019 |
ojtech8291: Am not sure I get that part, how is the input 24v, maybe you meant the battery input? If yes then that's fine, an intelligent CC/inverter will handle that easily. My GK series hybrid inverter has a voc of 120-450v and it only accepts 24v battery set-up. At the moment I have 6 panels in series (above 200v) and all is good. However ofcourse if he has funds he can go for higher amps CC I actually think by the time you get a above100voc CC it will already be a higher amps CC. |

Bros so I have done the setup; could not get a bus bar for now so I used the DC breaker as the common connection point for both the SPD and PV. However I have noticed that it seem the battery consumption has increased, does the SPD and DC breakers consume power on their own? Update nevermind the source of drain identified - it's self inflicted. ![]() Secondly, I have moved my stuff to standalone, I was happy to see over 1kw yday at relatively high sunlight. However when it rained and after sunlight came back I lost generation, noting was coming in, I noticed water was still on the panels could that be the reason why I was not generating anything?

Re: Solar Energy, A Complement To FTA by lexi28(m): 8:21am On Aug 04, 2019 |
ojeysky: hmm, the PV rack you have there looks curved and water seems to gather at the low point there. your controller, is it a pwm? or MPPT? I would advise remodelling of your PV rack to allow runoff of rain water rather than have it gather on your panels. that looks like a probable cause of no production. cheers |
Re: Solar Energy, A Complement To FTA by mctfopt: 8:30am On Aug 04, 2019 |
ojeysky: Water on the panel can not totally stop generation of power. I'm afraid the standalone system being that close to the building may experience some shadows from it. Check if your connection is ok. I'd suggest you give the solar panels some slight tilt, so that water can run off the panels when it rains. Even if it's 5 degree tilt from the horizontal. |

3 panels of 150watts each connected in parallel with 10awg dualcore cable to 60a pwm cc and 200ah battery. Distance from panel to battery is 25m. Juicecoming as measured on cc is 6.5. How come?

Re: Solar Energy, A Complement To FTA by mank1234(m): 2:27pm On Aug 04, 2019 |
earthrealm: You're right. My error. The upper limit too shouldn't be 50V. The point though I was trying to make is that 1) give an upper limit of Voc for a cc, it's not panel wattage that should determine how many should be in series but the panel's Voc. 2) that it's not wise to mix panel for a single cc cos of the differing specification even for same wattage panel. 2 Likes |
Re: Solar Energy, A Complement To FTA by mank1234(m): 2:37pm On Aug 04, 2019 |
ojeysky:Nothing to fear. It's GK and MK (axpert) bug. Some people have complained of loosing generation just after cloud shading. Probably, a future firmware upgrade may solve it. If you put OFF inverter and ON it again it will start working normally. Or after a little while it will pick up on its own. Otherwise by next morning it will work normally.

olaolu11: are you sure your battery isnt fully charged?. to rule this out, put on a load of uver 150w, then observe if harvest will increase, if it doesnt increase, then you may have a defective panel in the mix, use a multimeter and put it on dc current setting, measure each panel directly with the meter, and confirm all are ok 1 Like |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 5:07pm On Aug 04, 2019 |
Thanks for the information and for the reference, it came back alive in the morning. Just got home and I am generating up to 400w at the moment. At least it's an improvement compared to when I had it on the roof where I would not have seen anything by this time of the day. @lexi28 it's only one of the panels that store some water after rain, the rest just have sprinkle of water on them. Unfortunately we missed the panel measurement by a few mm so panel could not sit/fit well on the rack, I will try to re-tilt to avoid storage of water. mank1234: |

Re: Solar Energy, A Complement To FTA by olopan(m): 11:14pm On Aug 04, 2019 |
good evening everyone and @Olaolu11, I believe and suggest that your multiple panels could be an issue here, they are all not in sync i.e. from a single manufacturer ..... meaning they will work at the power and current of the least in the parallel connection and also note name plate dont mean it say what is written, shady business of wrongfully stating a panel to be higher than what its suppose to be could have happen. but the weather might have also caused the drop in amps. and even if the above was to be overlooked, the 10AWG - ~6mm2 cable that you have would make your voltage and usable amps to go to waste, so i'd suggest that you if you want to keep the panels and enjoy better amperage input, then wiring those panels in series would do you solid big time, a 30A Epever MPPT would be great .... but maybe after you might have settled down from the cable commitment you recently did. school go soon resume, eh! ![]() ![]() and lastly you need some serious cable management skills, check "cable porn" on Reddit .... sure you gonna be inspired. check the chart i made a while back for the AWG-metric conversion NB: with MPPT you'd get to keep your 6mm cables.

Namzy: This is impressive if it is really the fact. I can even sell the 6 months old Haier Thermocool for cheap and add some money to get this. But are you sure your 70 watts is not the recorded consumption on a 24 volt power inverter system in which case the wattage consumption recorded is always half of the actual AC rating of the appliance. Please the name plate on the appliance will be more persuasive. I am itching to dump what I have for this power saving feat of a deep freezer. By the way, below is the name plate of the Haier thermocool. Start up power draw is usually 167watt to 170watts. It then starts dropping and in less than 4 minutes, it drops to around 110 watts in most cases.
