Hello, I’d like to seek this community’s advice as to why my 18KPV is not properly charging. I’ve been working with signature solar (@SignatureSolarJess ) for a couple months now. They always take my call and always respond to email, but I feel like I’m just sent is circles with no progress.
What I’m trying to do: I’m trying to deep cycle my EG4 PowerPro batter by completely draining it to 46V and charging it to 54+ ~56V 5 times while in lead acid
Why am I doing this: When I work in Lithium Ion and work via SOC the 18KPV switches over to AC bypass way early with plenty of voltage left as the SOC and voltage are misaligned.
What am I doing:I’ve flipped my PV DC breakers so they provide no input, as the PV will charge the battery up before the battery is fully depleted. I have AC input into the 18KPV. I I have it set to begin charging from AC when voltage is 46v and stop at 56 volts; however, the inverter will charge the battery from 46 to 48~49 volts and stop. This results it the battery carrying the load until it’s back down to 46v OR it just flips to AC bypass.
What I’m trying to achieve: I have a 2nd powerpro battery and Signature Solar advises for the battery to be in Li Io and use SOC so the batteries can communicate better and be aligned, but I can’t have my 1st powerpro in SOC because it is way off from the Voltage.
What does seem to be working: When my PV is on, the PV+single powerpro in lead acid working via voltage works great, but this isn’t a lead acid, it’s Li Io and it’s becoming concerning that it’s been months and SS+me haven’t been able to figure it out. I’m just curious if next steps is a warranty claim.
Any thoughts @FilterGuy ?
I’ll attach an image of today’s data and my settings. Any and all help would be appreciated.
