My off grid kit

Still setting up the system and I am happy with my order but I never did receive the custom solar kit system schematic book that stated it was free with my order and it would be nice if the solar panels had the mounting hardware

First Off Grid Solar System!

Even though I Own a Service Company That Installs and repairs industrial inverters (VFD,s) for electric motors (for approximately 35 years), this was my First rodeo with an All in One MPPT charger and inverter.

I am quite impressed with the sensing capabilities and programming. The Output looks very clean on my o'scope under load and at Idle. The idle consumption is a little high! ALL parts of the system arrived within 2 weeks (be patient) Batteries were approx. 52 VDC and balanced on arrival.

Spare EG4 6000EX-48HV

I bought this unit as a "spare" for now and will probably parallel with other unit as load increases if needed. I bought this unit because I am running several inductive loads.
