This device does not have such setting - but from what I see your math rougly corresponds with what's happening - the amount of amps flowing into the battery drops significantly after 2-3hours of max charge - despite the capacity on the solar side - the load is reduced. My only worry was, that...
cross check that with the min and max mppt voltage supported by your controller and the decision will be simple...
my current panels have Vmp 42.35, and I rarely see them going above 31.8, so 8S as opposed to 4S/2P or anything alternative was a no-brainer for me... (especially that my...
but that's exactly what I am observing here... it appears that the "float" should kick in around noon (this is where the charge counter achieves 350-400Ah), and I usually don't have enough load to maintain the beautiful panel output curve because of that - I use additional loads (AC in common...
yes, it's configured to 100 amps, and it's set to 100 at the moment. But max I've ever seen from it was around 95 (it's the self-reported value, as I do not have the measurement shunt). The device does not have any advanced settings - you can choose the max charging current, bulk voltage and the...
I started evaluating various solar to AC scenarios to marry with this 3500W inverter from RAGGIE, and I successfully managed to power the LG dual inverter split 36kBTU unit dedicated for tropical countries (I38TKF), which during max load pulls around 2.7kW, while during sleep mode (which I use...
it is gel, not AGM. The battery label says "deep cycle gel", but besides that I can't find out any spec sheets, so I picked the values based on what I found about similar gel setup from Huawei... I adjusted the charging voltage to 28.2V (float 27.2) on the device and will keep observing.
Thanks...
thanks for your comment. I do not have the absorption end amp setting configurable in my controller, I can play around with voltages only and define float / bulk charge voltage. Last night the voltage did not drop below 24V, and today's charging was also very similar - just peaking at 29.9, not...
I am running a tiny setup with 6x 12V 200Ah gel batteries (huawei) - 3 parallel banks of double batteries. I am just starting (second month) and trying to figure out how to configure my solar controller to properly power these batteries and avoid sub-50% discharge. And I fail miserably day after...
