- Reduce diesel fuel consumption by up to 20%—on top of your existing solar savings.
- Accelerate the payback period of your Solar + Battery project by up to 4 years.
- Control- your generator so it works smarter, not harder.
In off-grid systems, traditional state-of-charge controls often cause unnecessary generator runtime—burning fuel, wasting solar, and driving up costs. Sponge changes that.
How It Works
Instead of relying on static “cut-in/cut-out” settings, Sponge uses intelligent forecasting and generator control to ensure your battery wakes up each day ready to absorb the maximum possible solar energy.
- On sunny days: Sponge keeps the battery low overnight, allowing full solar absorption in the morning.
- On cloudy days: Sponge coordinates limited generator runtime to ensure backup power without sacrificing solar harvest.
- Every day: Sponge minimizes unnecessary generator usage and aligns energy generation with real demand.
By actively scheduling generator operation based on solar forecasts and load predictions, Sponge reduces diesel consumption and optimizes your system for true energy independence.
Generator & Solar, Working in Sync
Without Sponge, your generator might start at the wrong time—charging the battery just before sunrise and wasting incoming solar. With Sponge, each day begins with the right state-of-charge to make the most of the sun’s energy, dramatically reducing diesel usage without compromising reliability.
