    PIP-1012LV Error Code 5.. What happened?

    Hello, I have owned the PIP-1012LV model since November 2021. Last week I disconnected all load from the unit. Only solar panels and batteries were connected for a week. Batteries were fully charged (solar only) and during nights the unit remained off. Today a "Error Code 05" appeared with loud...

    I'm I overpaneling Growatt?

    Hello, I own the Growatt SPF 3000TL (24 volts) with a 1.2Kw solar panels. I have noticed that sometimes all 1.2 Kw are coming into the system (consistently for about 15 minutes). Is that normal? My expectation according to some articles is a 75-85% of PV efficient. That would be like...

    Yes, you’re right. I will keep my 3k inverter. Thanks for your comment.

    A little frustrated after upgrading to 24 volts Growatt 3000

    Ok, I got it. Your math is clear and helped me to understand that watt hours remain the same in both scenarios. For which I appreciate your patience and your clear explanations. I learned one more thing, before Google anything about solar, I’ll come to this helpful forum. You hit the nail in the...

    When batteries are in parallel their amp-hour increase. This means more runtime. Isn’t it?

    Thank you, and that is the reason why I keep considering this option. More stored energy will benefit my load. The series arrangement is keeping me at 2,560 watt hour option. But also is giving me the benefit of solar energized appliances during sun hours, not bad at all.

    Good point! I feel like in the Twilight Zone ? May be I’ll keep my new Growatt and then I’ll see what to do. Thanks!

    Each battery has 200Ah, since I have two, total ah would be 400 (in parallel). I understand that by going in parallel I’ll have 2,560 watt-hour per battery (as per battery specs). Total would be 5,120 watt hours. Is this correct?

    I was considering going back to my previous 12 volts system and install the two batteries in parallel so I can have 400Ah (2,560 watts x 2 = 5,120 Kw. Not sure what to do…still considering my options.

    Thanks everyone for your valuable insights for this matter. I’ll try to upgrade my battery bank -which I did when going from 12 to 24 volts- and also more panels will hopefully help.

    Definitely, I’ll have to increase the size of my battery bank. I went with just two in series 12 volts batteries to make it 24 volts, but just with a 200Ah capacity. Thanks for your advice.

    A little frustrated after upgrading to 24 volts Growatt 3000

    Hello, I was at 12 volts LifePo4 battery @ 200Ah. A week ago I upgraded to a 24 volts system, I wired two 12v LifePo4 for a 24 volts series battery bank and a Growatt 3000 inverter. Last night after a blackout my battery bank lasted the same time as when I was @ 12 volts, same load. I wished...
