ESS-Diesel System

ETEK Solar ESS-Diesel Systems pair high-capacity battery storage with automated diesel generators without requiring solar as a primary source. The battery absorbs load spikes, provides spinning-reserve replacement, and allows the genset to run at optimal efficiency rather than cycling at light load.

This hybrid backup architecture is widely used in mining, oil & gas, manufacturing, and peak-load facilities, where diesel is already present but fuel and maintenance costs are high. By letting batteries handle short peaks and the generator cover extended outages, ETEK Solar ESS-Diesel systems deliver fuel savings, faster response, and more stable backup power.
