Energy, BESS & Solar
Energy efficiency, BESS sizing, DG → solar+BESS crossover.
Energy upgrades survive scrutiny when the assumptions underneath them are conservative and explicit. The BESS sizer, Energy & Efficiency Estimator and DG-to-solar+BESS crossover all expose their load factors and dispatch assumptions so the resulting kWh and CO₂ figures are defensible against any third-party model.
Vertiv, Delta and Fuji-class hardware sits behind the BESS sizing logic. The crossover calculator answers a single question — at what monthly DG run-hour does it stop making sense to keep running the genset? — and gives you the kWp solar and kWh LFP that breaks even on energy.

4 tools, sized for
energy & bess.
Energy & Efficiency Estimator
Adjust building variables and see indicative energy and CO₂ savings (kWh) for a BMS-driven energy upgrade plus daylight-harvesting LED retrofit. Conservative; defensible in a first conversation.
BESS Sizer
Peak demand + solar + storage strategy in, indicative LFP battery size, inverter rating, daily throughput and cell life out. Vertiv, Delta and Fuji-class deployments.
DG → Solar+BESS Crossover
Diesel rate, DG capacity and monthly run-hours in — the kWp solar + kWh LFP BESS that breaks even against running the genset out, plus annual diesel litres displaced and CO₂ avoided.
UPS Runtime Estimator
Critical load in kW + redundancy target in — runtime per battery string at 100/75/50% load, recommended VA rating and the load-vs-runtime curve. Online double-conversion UPS only.
