Anyone found a source for a power supply similar to what Solar-Assistant sells? https://solar-assistant.io/shop/products/dc_usb_psu Their price is great, but shipping to USA makes it unreasonable.

Anyone know what their inverter is based off? Doesn't seem terrible for 10kWh battery capacity.

I have 2 eVault Classics, so I am not using battery-inverter communication. I installed Victron Smart Shunt and configured it as follows: Battery Capacity: 720Ah Charged Voltage: 54.4V Discharge Floor: 18% Tail Current: 2.00% Charged Detection Time: 3m Peukert Exponent: 1.05 Charge Efficiency...

I have a few Longi 445W panels (VOC 49.1V) left over from building my main system at home. I'd like to re-use one of them for a small 12V system to power the lights and heater in my chicken coop. I need to find a charge controller that will work with one (or two) of these panels.

I am wiring a 22kW standby generator to my Sol-ark inverters. The installation manual says control wired need to be in their own conduit, but that's referring to the wires running to the transfer switch. I won't have those, since I am off-grid. Do I need to run a separate conduit for the...

SKU number: 458-00252-32 I have 20 of these units, would prefer to sell all at once $25/each Also have the TIGO RSS transmitter (490-00000-10) $40

2 12k units, with 2 eVaults. This afternoon, batteries were fully charged, full sun, batteries were in equalization state, getting 54.4V. I turned on my circular saw and the whole system shut down, with AC overcurrent fault. The load on the system at the moment was only 400W, circular saw is...

It's a 24kW generator, and my solar inverter can only pass through 12kW, so I'm looking to have the ability for some specific 240v equipment to run directly off generator. The rest of the time I want the ability for Sol-ark to turn it on/off for backup use.

I am undecided on the battery for my 12k Sol-ark. I want to make sure I am not missing other potential solutions. I prefer a set-up with 2,3,4 battery units to a single larger battery bank, for redundancy. I am not as much concerned with price, as with reliability and support. Integration...

Still trying to design my off-grid system. I have 20 445W panels, arranged in 2 strings of 10 (2S5P), each feeding a Victron 150/85 SCC. Here are the specs I calculated for each string. Rated PV Array Power 4450 Watts Anticipated Array Power @ 40 C 4216 Watts Rated PV Array Current 53.9 Amps...

My plan is to install 20 JA Solar 405W on the roof of my barn, (VMPP) 41.60 V (IMPP) 9.74 A (VOC) 49.86 V (ISC) 10.39 A I am trying to size the charge controllers I'll need. I am going with Victron stuff, as I can get a very good deal through a friend. According to Victron...

I am planning to get a Sol-ark 12k for my off-grid system. Starting off with 20 400W panels on the roof of my barn. Easiest would be to just make 4 strings or 5 panels each and run each directly to 4 PV inputs of the Sol-ark, right? Eventually, I will be adding another set of panels, on the...

Please bear with me as I figure this out. We're making a move to a property that will be completely off-grid (the cost of running power line is roughly $20k), so I am 99% decided to just go with a solar system. I understand the principles, however my only experience with off-grid power is...
