I recently purchased 4 of the eg4 lifepower batteries to replace my 48v crown cr430 flooded lead acid setup. I installed the four batteries in the rack made for these batteries and checked voltage on each module before paralleling. All modules showed 52.8 volts. I set all of the dipswitches as required in the manual (manual is wrong btw) and turned on each battery one by one checking voltage at the bus bar with each battery. With all batteries installed, i had 52.8 at the busbar. I connected the inverter cables and checked voltage at the 250a breaker. It showed 52.8. I turned the dc breaker on and the inverter began clicking and the fans began pulsing like the unit was trying to power up. After several seconds the batteries alarm light lit up and i turned off the breakers. The inverter never powered up long enough to even light up the display on the scp. Upon turning battery breakers back on, they showed no issues. I can't figure out why a perfectly functioning system suddenly won't recognize these batteries as a good power source... or at least i guess that's what is happening. After not being able to get these to work, i re-installed the fla's and the inverter fired right up?!
The system has been in use for about 15 months now with minimal issues outside of the frustration of fla batteries. I can't wrap my head around this issue. Voltage is voltage right?
I spoke with the techs at signature solar and we went through each module and the batteries are showing 100% health with no errors.... even though the alarm light came on and voltage was cut. All parameters are in spec it appears. They are speaking with the manufacturer tonight for possible remedies.
I also spoke with the folks at Schneider and they are sending me on loan a home insight system so i can run updates on the software. They said the version I am running is 9 updates out. I don't really think this is the issue but i'm going to update anyway. I always thought most inverters, Schneider included, were battery agnostic. Is this correct?
Any thoughts or ideas would be greatly appreciated. Im banging my head here and my back is killing me after moving 2400lbs of batteries all over the place.
Thanks!
