I've run three SOK 200AH batteries in parallel for a couple of years now and the BMS has never been accurate. Really don't need to bother with it as with a decent battery monitor it tells you most of what you need to know anyway. I will say these are definitely good batteries though all three...

I have panels on both the south and east sides which is helpful in winter with the low sun angle having eastward panels but mine are in parallel into a combiner box so there is no issue. If your panels are in series I think I would do two strings with one string on the East and the other string...

I just bought an EG4 9K unit today. Went with the DYI option with the pre-charged lines. I was hemming and hawing about getting a cheaper unit off of Amazon and just pulling the vacuum myself but what really drew me was how efficient this unit is with the SEER2 of 29.5 and the HSPF2 of 10.7 so...

More panels on the south of course. I have four panels on the east which come into play more during the winter with the lower sun angle as they are mounted on a gambrel style roof with a pretty sharp angle which works real good for the lower sun during the winter. I did that to help more with...

I had sent an inquiry to Outback about the settings for Lithium batteries and what could be done to up the voltage enough to properly charge the batteries. The following is what was sent to me. FWIW the clouds have cleared out a bit and seeing some more sun and the outback is outputting 14.2...

After watching a number of Will's videos I went with the SOK 206ah batteries. I bought two of them (running 12 in parallel) and just bought a third one last week. I just ordered the standard battery at $1029 but was pleasantly surprised when I was sent the bluetooth model for both the two...

Thank you for your comment. Not that I'm doubting you but how can it be that if using photovoltaic alone and so far with the current settings of the Outback I'm seeing a maximum output of 14.2 volts how is it possible to get to a state of charge of 14.6 volts? Once the battery bank gets to the...

I think it’s wired correctly. The panels are all 12v nominal wired in parallel. High overcast today and at this moment 200 watts output with 15.8 volts input. In full sun it’s closer to 16.5 volts input or so. Perhaps it isn’t an issue as of course as the input voltage goes up in MPPT so...

The system is just for my radio room for emergency communications as all the radios run 12 volt along with led string lighting, etc. Also have a Honda 3kw generator if needed. I have only run the panels in parallel and into a combiner box and then into the charge controller. The charger is a...

Hi; Just signed up although I have watched the videos for awhile on Youtube. I have had a 1kW system for quite a few years and finally made the jump to the recommended SOK batteries. I have a Flexmax controller as well that I bought in 2019 and I have the same issue as the OP. Question that...
