It’s a power system that blends two or more sources—typically solar PV plus a diesel/gas generator, often with batteries—to deliver reliable electricity at lower cost and with better power quality than diesel‑only. The controller decides which source runs when, based on load, battery state, and sun/wind conditions.
An off‑grid system relies mainly on PV and batteries and uses a generator only as backup. A solar–diesel hybrid actively coordinates PV, batteries, and the generator to reduce fuel use and runtime while maintaining power quality for heavier or variable loads.
Some hybrid inverters can export to the grid when net metering is enabled and configured. Others operate in “zero‑export” mode, prioritizing on‑site loads and batteries without feeding power to the utility. We clarify behavior during design to match your compliance and billing needs.
Key drivers include PV kWp, battery chemistry and capacity (kWh), inverter/controller class, generator rating and features, BOS components, and site logistics. Quiet‑hour targets, surge demands, and remote monitoring also influence the budget.
Often yes, if loads are prioritized and the system is sized for real usage. A 5 kW kit suits small offices and homes with modest motor loads; 10 kW provides extra surge headroom for larger spaces or multiple ACs. Actual suitability depends on your peak/average load and desired backup hours.
PV needs periodic cleaning and visual checks; batteries need temperature and connection checks; inverters/controllers need ventilation clearance and firmware updates; generators still require oil/filter changes but far fewer runtime hours than diesel‑only setups. We provide an O&M schedule at handover.
