Hi, so i just pretty much got the core setup installed. I could not run a darn thing. Finally tracked it down to the BP220 i just put in. I have a 250AH battery at 24.4v, when i bypass the BP220 the v stays pretty stable and no alarms. With it connected the V drops to 14v, like it cant pass thru...

Hi all - I have most of the parts to setup my system (small shop).. since the panels charge 9.5 a at 48v does the controller increase the current for a 24v batt system? I have 2 400w 48v panels on the roof, and a 24v battery system. 100ah lifepo4 pack on its way but i wanted to buy 280ah. Below...

Hi all - trying to finalise a diagram for my setup im tackling next few weeks - 800w 48v panels 20a max ===> 50amp 2 pole breaker/disconnect for both wires ===> Victron 100/30 controller ===> (Neg goes from controller to battery) / Pos goes through 40amp (or 30amp?) single pole...

Why not just use one of these units instead of stacked inverters for split phase operations? Or does it just split the DC into tso DC output streams (ie no inversion).. I did read that they do draw quite a bit of current on standby which I dont like, where as my current inverter is a toroidial...

Hi there - calculator says amps is 16.6, so would a 20a controller handle these 2 panels? 800w/48.8=16.v, specs show 19amp correct? 20a victron should be fine then yes? Panel data (400w column): (edit:) Battery bank is 24v.

Hi busy researching bms for my tesla battery, not sure what model battery this is? Found an ebay match for model s/x 5.2kwh 250ah but wanted to be sure? Also possible to test capacity?

Ok so first off the bat - picked up the Tesla battery 2 days ago from an ebay seller, it was at 17.5v when i checked this morning. Is this a problem? Had it charging today using wills params on his page below, got up to almost 22v before sunset (was a super cloudy day here).. (his tutorial is...

Hi all - I have a shop and looking into investing into a solar system. 99% of the time I charge power tool batteries and run maybe 60w of shop lights on 110v. Once in a blue moon I need to run my compressor for sand blasting - its a 3HP 220v, last time i calculates the start draw is around 45...

Hi all so finally got my solar setup complete - now that ive used mostly victron I guess i have to doll up the notes and drop $ for a decent inverter. The cheapo unit is giving me work anxiety! fwiw - i own a small marine repair business and 100% off grid. Mostly run power tool chargers, some...

Hi all - so received my victron 100/30 controller and waiting for quotes on batteries (will be going with lifepo4 cells 280ah or 320 ah) - Inverter will be around 5k to 8k maybe 10k.. What size BMS do i need? Can i not just buy the largest one? Why match? Can get a 500a unit that I believe I...
