Grid/Gen Switching
Across Asia, Africa and Latin America, communities, clinics and schools depend on expensive diesel generators — or go without power entirely. Diesel is noisy, polluting, costly, and fails supply chains in remote areas.
For NGOs and CSR-funded projects, the challenge is building energy infrastructure that's reliable, low-maintenance, and financially justifiable over a 10–15 year project horizon.
Diesel Cost
USD 0.30–0.60/kWh, rising every year
Noise & Pollution
CO₂, NOₓ emissions — unacceptable near clinics and schools
Supply Chain
Fuel delivery unreliable in remote and disaster-prone areas
Lead-Acid
Short lifespan, acid leakage risks, frequent replacement cost
The Deye BOS-B C&I ESS is a factory-integrated system — no separate solar inverter required. Solar DC flows directly from the MPPT module into storage and load.

SUN-STS500L
Diesel gen backup optional
Solar Panels
Up to 200 kWp
MPPT Module
180–850 V DC
BOS-B Battery
768 V DC bus
PCS Module
100 kW AC/DC
STS Module
Grid/Gen/Load
AC Loads
Community power
Grid or diesel generator connects to STS for backup — automatically engaged in <20ms when solar + battery cannot meet demand.
Power health clinics, schools, water pumps and emergency shelters in off-grid and disaster-affected areas. Eliminate diesel dependency permanently.
Fulfill your Companies Act Schedule VII obligations with high-impact, auditable clean energy infrastructure. Measurable CO₂ reduction, ESG reporting ready.
Deploy grid-edge microgrids to electrify last-mile communities, stabilise weak-grid areas and meet renewable energy targets under national and state programmes.
Uninterrupted power for cold chain vaccines, surgical lighting, oxygen concentrators and electronic records. 193 kWh usable = 10–12 hrs of critical load at night.
Power classrooms, computer labs and e-learning systems in areas without reliable grid. One BOS-B cluster powers a 300-student school for a full school day.
Solar-powered water treatment plants and community pumping stations. Consistent power eliminates hand-pump reliance and diesel pump costs.
Power remote cell towers, satellite communication hubs and emergency broadcast infrastructure. Eliminate generator maintenance in hard-to-reach sites.
Replace 100% diesel generation on islands and eco-resorts with clean solar storage. Dramatic fuel cost reduction and carbon footprint elimination.
Rapidly deployable microgrid for post-disaster emergency response camps. Rack-mounted modules reduce site setup to days, not weeks.
