Energy, BESS & Solar
ROI, BESS sizing, DG → solar+BESS crossover.
Energy upgrades survive scrutiny when the assumptions underneath them are conservative and explicit. The BESS sizer, ROI calculator and DG-to-solar+BESS crossover all expose their tariff curves, load factors and capex assumptions so the resulting payback is 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.

Energy & BMS ROI Calculator
Adjust building variables and see indicative payback for a BMS-driven energy upgrade plus daylight-harvesting LED retrofit. Conservative; defensible in a first conversation.
BESS Sizer
Peak-demand and tariff curve in, indicative LFP battery size, annual savings and payback period out. Vertiv, Delta and Fuji-class deployments.
DG → Solar+BESS Crossover
Diesel price, DG capacity and monthly run-hours in — the kWp solar + kWh LFP BESS that breaks even against running the genset out, plus capex, payback years and CO₂ avoided.
