Hi, Sorry if this is a dumb question but I’m still new to all this solar stuff. I would like to know whether it’s possible to charge a 24 volt battery with one 330 watt solar panel which has a Vmp of 37,2 volt. Thank you in advance.

Hello, I am still fairly new to this solar stuff, so I hope this isn’t a silly question. I have just installed a Growatt SPF 3500ES inverter to help power some appliances and to power all my lighting in my house. It is connected to nine 335w solar panels and eight 115Ah lead acid batteries...

Hi, newbie here I´m afraid. I have set up a small off grid system at home, just to deal with some power outages we have here, so we can keep the TV, Internet and fans running. I have an Epever 60A charge controller, hooked up to my solar panels, and six 115 Amp batteries connected in series and...

Long time lurker on this forum after watching hours of Will´s videos. I´m English, raised in The Netherlands and have been living in Brazil for 10 years now. Despite being a country with HOURS of sun a day, solar power generation is still pretty uncommon. Because we often have power outages, I...

Hello, sorry in advance if this is a silly question. i have made a very simple solar set up on which I run a 1000W inverter during the day, and use the full lead acid batteries at night to power 6 led 8W 24V lights for the veranda. These are powered directly by the charge controller’s DC outlet...

Hello, I have this all in one Growatt hybrid inverter but am having some problems with the AC output voltage. The power I receive from the grid is only about 205V but I have set the inverter 220V and 60Hz as is normal where I live. When I set the inverter to solar only, SOL, the output...

I have been using the Growatt hybrid inverter for more than 2 years now with lead acid batteries, and have never had a problems. Recently I bought a Narada 48NPFC100 battery (details in attachement) which are used a lot in Asia, South Africa and Australia. I live in Brazil where it is difficult...

Hello, I have Growatt SPF 3500 ES hybrid inverter and now have nine 330W solar panels connected in series as the inverter can handle up to 430 Vcc. To add more panels I would have to build two arrays of 6 or 7 panels, and connect the two in parallel. I would really like to know if it’s OK to...

Hello, I hope this isn’t a silly question, but I don’t really understand what my Growatt Shine app is showing me. I have attached two photos which show how much much energy my panels have produced, how much I imported from the grid, how much battery power I used (storage power) and how much...

Hello, About 4 months ago, I exchanged by 8 lead acid batteries for one LiFePO4 100Ah battery, made by Unicoba, which is a renowned company with decades of experience in manufacturing batteries here in Brazil. At about 10:30 pm every night, I switch the inverter, a Growatt SPF3500ES, to battery...

I have ten 330W panels in series about 100ft from my inverter on a 48V system. There’s another 330W panel I used to use for another smaller 24V system, which now is no longer in use. This panel is about 20ft from my inverter. My inverter supports up to 500V VDC, so I was thinking adding the...
