    Growatt LVM3000es trips GFCI on input when trying to charge

    I have a Growatt LVM3000es 48v which trips the GFCI feeding it's a/c input when charging from grid. I'm guessing this is a neutral ground bond issue, but I can't find any info on it in the manual https://signaturesolar.com/content/documents/GROWATT/1519009-manual.pdf Is there a screw inside...

    I'm confused on victron mppt 150/45 solar limits

    I searched and can't find the answer, even though I'm sure it's probably been answered a million times. I bought a smartsolar 150/45 and I guess I need to know what the overpanel limits are. The specs for it say 150v input max and 50a input current, which leads me to calculate 7500w max panels...

    Did I get scammed for $3100? Vpment 12v 200ah batteries a scam? They only weigh 34lbs.

    I won an ebay auction for 8x brand new vpment 12v 200ah lipo4 for only $3100, (I know, too good to be true) and I actually received 8 batteries labeled that. They look identical to powerqueen 12v 200ah, they claim 200ah BMS inside, except the weight is way below my ampertime 12v 200ah or any...

    Signature Solar and shipping damage, are you a victim too?

    I bought a pallet of 10 panels, the 440w mono ones recommended on here, 1 panel arrived broken. There was no damage visible from the outside, after I got to the last one I found it was cracked glass and the panel bent, by what appears to be the straps used to tie it to the pallet. I sent pics...

    Help me choose solar panels for most power on RV with growatt 24v 3000w please

    I have an 18' stepvan with about 21' by 7.5' of roof area that I want covered as much as possible with solar panels not just for power but to cover for shade and quite down rain on a noisy roof. These need to be the right fit for a growatt 24v 3000w 120v setup with two 12v amperetime 200ah...
