Hi all,
Anyone have experience with similar equipment that can chime in and let me know if this is normal?
I have a sol-ark 15k and 30kWh of Pytes 48100r batteries. Previously I was running my battery down to about 40%, then getting whatever sun I get, but since I have bumped up the low-end of the battery % before going to grid to get a fuller charge. I have a starter 2kW array in until I get the full 19kW array installed soon.
When I charged say from 40-55% during a day, the charge went up by about 1% every 15 mins of good sun. Basically it went up in steps, like you would imagine it would. Now when charging today from 83% and going up from there, it seems to sit around 90% for a long time. Today, in good sun with a steady 1kW+ going to the battery for over 5 hours, it barely budged the % charged. Started off going up, then sat at 90% for 4 hours.
Normal or no? Is there some kind of change in charging procedures at around 90%? If it charged that long and the battery voltage didn't change much for hours, and the battery keeps taking the full 1kW where is the power going? Just a sensor or algorithm in the Sol-Ark that is still learning the battery bank?
I have full coms on CanBus with the Pytes batteries and their BMS says the same thing. Wattage going in, but SOC and voltage not changing much over many hours.
---------------
So to anyone with a similar setup. Ideas? Normal? Not enough wattage to get past a certain point in the charge cycle (absorb?). I don't want to change settings or call support unless it is an issue. I can give it a couple days too to see if it is a consistent thing.
Thanks!
