ESS 8-1i

ESS 8-1i

Solar Battery System

For medium to large households


The ESS8-1i is our classic solar battery system, designed for optimal performance for medium to large households. It stores low cost off-peak energy for use during expensive peak periods.

Surplus energy from your solar system is stored for use during periods of high demand and when solar power is not available. An intelligent controller selects the most cost effective energy source automatically; use of this system can dramatically lower your energy bills.

The ESS8-1i supports internal lithium polymer battery systems (BP4, BP8 or dual BP8, supplied separately) and includes full battery management, an integrated MPPT controller for solar panel input, a high capacity mains charger to support time of day battery charging if desired, as well as an auto-start output for generator control in off grid applications.

The ESS8-1i is easily monitored and configured via an app running on your smart phone* which provides graphic displays of the system status (*due for release shortly).
