Hi, the voc of 12v panel is much more than 12v, usually 18-22v. So you'd better not to connect all 5 panels in series. You may have already hit the limits of the 68v voc. Check the panels' spec and get to know their voc and Isc first, then make the decision.
Hi, the best way to keep a Li-ion battery healthy is charging and discharging at 0.1C, which means the current should be 0.1*100AH=10A. How many batteries are needed bases on how many power you will need.
Even though vertical installation would have less heat absorption and higher output, the force area also matters since vertical installation will make the panels more vulnerable than horizontal. Tilt bracket is a good choice for solar panel. It can keep the panels cool and get natural breezes. A...
Pretty amazing! It will be a nice tool for solar builders and beginners.
Just one more little thing..some famous brands cannot be found in the drop down menu. Will you update the list in the following versions?
Hi, you can have it as a large battery backup, but the battery bank of solar system should consist of same batteries.
Therefore it will be your loss if you wanna make 30 kWh battery storage with other batteries. Yeah I think it will be only loss.
If you would use the rack battery as part of...
Read lots of Chinglish instructions too lol.
I am guessing the words "During the charge at the low temperature, current limitation is applied" means when the operating temp gets close to 0℃, the charging current will be reduced.
You should still keep it working in that range.
Tbh I think a 10-year warranty is quite enough for an inverter. I am not talking about its quality, but the market changes too fast.
For example, maybe 5 years later a stronger one is created or new technology comes out, and you would like to buy a new and upgraded one.
The extended warranty...
Yes I understand how annoying picking up and rebuilding are. Now I know the reason why you said 4 bolts are "only" ? looks like drilling more holes in the frame is a must do.
Hi, could you tell me exactly what question you have with the eco-worthy 100ah battery? Eco-worthy supports every product with warranty. You can contact customer service for a replacement if you got a fault. The contact info is written in the manual usually.
The wiring is all the same to L/N/G. Most American devices are 120Vac, but since the water heater runs at 240v, I think it will work with the 240v inverter.
As far as I know the largest inverter Eco-worthy has is 5kw so I doubt it could meet your needs. But they offer good customer service. Any quality issue will get resolved.
Tbh I have to say it reads more like an article written by a non-native speaker student ? very formal, speaks like a book. I knew it cause I was one of them?
I would say 2*200ah batteries will be better than 4*100ah. More batteries need more wiring and lead to more potential issues like bad consistency. More batteries mean more troublesome if one of the batteries were faulty. The fewer, the better.
Hi, The Growatt 3kw inverter you listed only supports 24v battery system but the battery you wanna buy is 48v 100ah. I am afraid they cannot work with each other. You'd better find a 24v battery over 48v.
I think the company should be primarily responsible for this problem, not the country it comes from... prejudice is not good:oops:anyway, you should call the after sale service, pushing them to sort it out. It's what they must do as a seller.
I agree with flexible solar panels which are too fragile and not that much "flexible" at all. It often happens the panels got invisible cracks inside, leading to huge drop of performance.
