Re: [RE-wrenches] Midnite AIO Generator Functionality

Jason, Cant you just make the AGS turn on the generator before the inverter gets to the LBCO? Maybe this is more difficult if you do not have closed loop comms and the SOC drifts. I am just working through my first Midnite AIO setup now, so I cannot speak to the nuances of how it will work with tha

[RE-wrenches] Sol-Ark battery calibration

Does anyone know whether you can calibrate the battery voltage on Sol-Ark inverters? I am on site with two 12k-p inverters. My meter agrees with one of them, and the other inverter (the master) is displaying 0.6v lower than both my meter and the other inverter. I have gone through two tech support

[RE-wrenches] battery vent control for lead acid

Hi all, What are people using these days for venting a good ol' 48v flooded lead acid battery box? I am upgrading an off grid system. There is a one year old set of flooded lead acid batteries, so those will stay, but everything else will be new. I plan on using a Sol-Ark inverter. The existing ba

[RE-wrenches] Sol-Ark Dark Mode

Hi All, Does anyone know what it means when a Sol-Ark display goes into dark mode? Instead of the normal white background and coloring, the background goes to black, and the arrows are purple. I've talked to tech support, and all they would tell me is that it is "not good". We reset the dongle and
