I have a Victron 150/## MPPT that shows battery voltage level (eg 52V) as PV voltage at night when it should show near zero Upon researching it appears the most likely reason is a broken reverse diode. Victron staff commenting on identical issue: “the charger should switch to off mode during...

Picked up a pallet (20 panels) of these used panels Signature Solar just got in. https://shop.signaturesolar.us/products/208w-60cell-silver-poly-solar-panels-by-powerlight I tested two of the panels at random got 175w and 180w, which was A-ok by me. test context: - used a “WS400A” auto mppt...

I want to add some panels and trying to determine if I can add some different panels and they’ll still play nice if combined (paralleled) with existing setup. Current strings are VOC 112.8, max power current is 8.27 amps. New strings would be VOC 137.6, max power current 7.24 amps. 4 of the...

Summary: Lucked out on Quality. Slow to ship due to stock issues. Experience: - ordered April 4: $484 out the door for (4) Eve 280ah - they contacted me April 15 asking to change cells to CATL 271ah - I missed that communication and never responded to them until weeks later after seeing they...

Is there a way to get MPP Solar (1012LV) to never charge from utility, but leave utility connected to it for bypass purposes? My scenario: - powering computer that needs to run 24x7 - I want MPP to power it with battery until X voltage, then switch to utility (setting 12) - utility should only...

What I’m hoping: This is an off grid system and I can risk the panels/property by skipping grounding, while life safety is covered by PV combiner box w/ breakers on each string of panels. School me if I’m wrong, I’ve done my research but this is my first system. What I’m not worried about...

So I've tried to reach Santan Solar the following ways: 1) Called multiple times over the past 3 weeks -- always got voicemail. 2) Left a voicemail twice. Nobody has ever called me back. 3) E-mailed both their sales address and a named person. Nobody ever e-mailed me back. 4) Filled out the form...

I’ve struggled on this simple topic after several hours of research… All the Z brackets I’m finding seem to be for 100w or smaller panels. Panels: Twelve 250w, 5.5 x 3.5 ft, 42 lb solar panels (santan solar used panels) Structure: existing wood patio cover (~8x8 structural beams and ~2x2...

4 items that I ordered from China before changing my mind and deciding to go with a 48V system. All of these items are brand new, ordered via Aliexpress at the links listed. I haven't even opened the packages, I'll just be putting now shipping labels on and sending them to you. I am listing...

Is there any way to get Victron gear below their minimum advertised price (MAP)? The lowest price you’ll find online is the same everywhere online due to MAP. I’ve been able to find where I can buy it at MAP out the door (ie free shipping, no sales tax) but no lower. I’m looking to pick up: -...

I've searched the forums, google, and Will's videos looking for idle consumption of Giandel 3,000w 24v pure sine wave inverter and can't find it. I'm trying to decide between 2,000w and 3,000w. Giandel manual states 0.9 amps for 2,000w and 1.0 amps for 3,000w but I find that hard to believe...

Trying to choose BMS for 24v, 8s battery (8x 280ah EVE cells) that I will pair with a Giandel 3,000w inverter. It will have two Victron 100/50 MPPTs so 100a max charge. I’d like something with Bluetooth/mobile app. I’d like something a bit oversized for longevity so it can handle a constant...

Will this over panel work? 12v lifepo4. 4x 250w panels with the specs below, in 2s2p Rated Power: 250W Open circuit voltage (VOC): 37.6 V Max power voltage (VMP): 30.3 V Short circuit current (ISC): 8.85 A Max power current: 8.27 A

I was just testing my MPP Solar 1012. setting 1 is SBU (solar first, then battery, then utility/grid). I plugged in a computer and when it switched to utility, the computer lost power long enough that it was forced to restart… is this the norm or are there some settings that will make this...

Newbie so probably something obvious I’m missing… I have two panels I’m testing - rich solar 100w portable (https://richsolar.com/products/100-watt-portable-solar-panel-black) connected to an MPP solar 101LV. if I connect either panel alone, the MPP sees them. if I connect both panels in...

Model 1012MV-LS. It is plugged into utility power and battery, no solar. When I flip the switch on the MPP Solar, so that the inverter is "on" -- the MPP solar does not charge the battery from the utility power. When I flip the switch so the inverter is "off" the battery charges off the utility...

Any tips on where one can find a surface mountable USB-c PD 100 watt to install into the DIY solar generator I’m building? I’m building in a portable box so I’m looking for something where the external plug is something like the attached photos — ideally mounted in a round hole. if there’s an...

I’ve got the 1012LV-MS incoming to build my first system. Spec is 102 VOC limit for solar panels, 500 watts, So I’d id like to use 5 x 100 watt panels. But the VOC specs for all the 100w panels I’m looking at are about 21v-22v. 5 panels in serial would be 105-110 VOC, just over the 102 limit...
