So I spend a lot of my time (work) in locations without power. Support equipment is powered by a DIY 66ah/25v lithium battery driving a 500w inverter. My lidar scanning drone and bathymetry boat are chaged using a 90ah/48v lithium pack directly. New gear requires about 1500w at 120v, so I need a new system lol. So far I have a set of solar panels at 400w and I'm assembling a 600ah/24v LiFePO4 pack using 300ah cells in a 4s2p configuration. To simplify things I was hoping to find a charge controller/inverter that didn't cost a fortune. So far I found a Victron EasySolar-II GX, which does everything I need. But it's not cheap! Any other options? Thanks!
