Impressive all in one unit.

After over 30 years off grid using a pair of Trace 4024s I have begun an upgrade to modern technology. Installing a single 12000XP in place of the two 4000w units was childs play and the single 12000XP replace additional equipment as well with the built in charge controllers and circuit breakers. Paralleling a second 12000XP was just as easy. It is build quality is excellent. My only negative is that I can not monitor it on the local network without internet, which does not exist at site.

EG4 12000XP

This inverter is absolutely a beast! I'm am extremely happy with this product and how well it preforms. I went from using 100+ kwh a day on my utility company to less than 19! Once I add more panels and another battery, i should use less than 5kwh a day on utility.

12000XP with Lifepower4 V1 & V2

Love this inverter so far, just remember to install the latest firmware to eliminate the EPS overload fault on any load ~500w or more. Replaced a couple of Growatt 5000ES in parallel and handles loads better (EV charger) and the light flicker I had with the Growatt is gone. Transition from V1 to V2 battery communication cable must be modified to work correctly. (use pins 7&8 only) all other cables as supplied. Online monitoring easy to set up, battery communication worked right away.
