Reliable backup power, without depending only on diesel
DE designs and deploys battery backup systems that protect critical loads, reduce diesel usage and improve energy reliability for your operations.
Diesel keeps you running, at a cost
Many businesses rely on diesel generators for backup. Generators work, but they bring recurring fuel cost, maintenance, noise, emissions and operational uncertainty, and every outage still means seconds of downtime while they start.
Battery backup that supports critical loads instantly
Battery backup reduces diesel dependence. For many sites, pairing solar generation with storage combines everyday savings with resilience.
Built for the moments that matter most
Peak shaving with solar
Batteries discharge during peak-tariff windows to cut demand charges and high time-of-day rates, then recharge from solar for free the next day.
Diesel replacement
Reduce or eliminate diesel run-hours entirely - cutting fuel spend, emissions, and the operational hassle of storing and hauling fuel.
Fast, zero-gap switchover
A diesel generator can take up to two minutes to kick in. If a production batch is mid-run, that gap is enough to spoil the entire batch - a cost that's often impossible to recover. Battery backup switches over in seconds, so your operations simply never stop.
