I decided to abandon this idea; I went as far as ordering an aolithium server rack battery, and then started reading posts saying the AOLithium rack batteries were alarming for over voltage at 56.0 volts, which is regularly exceeded when the E1500LFP charges. It would still probably work, but I...
Well, I wired it up and it works as intended! The pecron is connected to both the transfer switch that powers the room with my pellet stove, and the AC input being powered by a separate circuit. It's running in UPS mode just fine and when I kill the power to the main panel it's powering the...
The two-pin MJ32 plug fits perfectly on the Pecron battery expansion port. It looks like a solid unit. I'm putting a generator transfer switch in so I can move everything away from the pellet stove, and then I'll buy the server rack battery.
I don't think you're wrong, but this is also the same as when the pellet stove is plugged straight into the pecron (which is the situation I'm in now). There is definitely not an internal N-G bond when the pecron is running isolated from the house; I'm measuring ~47 vac from output neutral to...
I have a Pecron E1500LFP I'd like to run in UPS mode to automatically power my pellet stove when the grid goes down. From everything I've read, using a transfer switch that only breaks the hot (i.e. all the normal Reliance products) will create a neutral-ground loop if you connect the solar...
Some additional data points:
Fully charged (like end-of-charge, not charged-and-rested) the E1500LFP external port reads 57.3 vdc. I ran mine tonight until it shut off and it looks like the BMS kicked off at around 43 vdc (hard to tell as it dropped quickly when an unexpected load kicked on...
It should also be totally possible to charge the E1500LFP with a 16s LFP battery through the MPPT DC connector, but in my case I want the E1500LFP to both charge and discharge the server rack battery since I'm using it as a UPS. I'm more of less using it in place of an off-the-shelf hybrid...
Disclaimer: None of this really make sense from a "build it from scratch" standpoint, and I realize that. I also realize that a bunch of the readouts on the Pecron, like state-of-charge are probably not going to work correctly. I'm doing this because I like to tinker with stuff, and I'm posting...
