50KVA 50kW+112kWh BESS Solar System

A 50kW BESS combines a 50KVA bidirectional inverter with a 112kWh LiFePO4 battery bank. It is the entry point for commercial storage: large enough to carry a clinic, a guesthouse, a retail chain or a small workshop through a full evening load, small enough to fit a single cabinet and a modest budget.

A 50kW BESS typically serves sites consuming 250 to 450kWh per day. Where a diesel generator would burn 15 to 25 litres an hour, the same load served from a 112kWh battery recharged by solar runs at a fraction of the marginal cost. Our BESS price and import guide breaks down the payback maths.

The rule for a 50kW BESS is to size the battery on overnight energy and the inverter on surge current. A guesthouse drawing 5kW through a 14-hour evening window needs 70kWh, comfortably inside the 112kWh usable capacity even after accounting for a 10-year degradation curve.

On the inverter side, 50KVA covers the simultaneous start of air-conditioning compressors and a borehole pump. Where loads are split across three phases, our engineers balance the phases at design stage rather than on site - the same method used in our 50kW 24-hour hybrid system.

Every 50kW BESS uses grade-A LiFePO4 cells with a BMS that reports cell voltage, temperature and state of health to a remote dashboard. The bidirectional inverter supports on-grid, off-grid and hybrid modes with built-in MPPT, so a later solar expansion does not require replacing the inverter.

Battery chemistry is the deciding factor in service life: LiFePO4 delivers 6,000-plus cycles against 1,500 for lead-acid. See the modules we use in our 30kWh battery and rack-mounted storage battery.

Mars Solar ships 50kW BESS units directly from our factory, which removes two or three layers of distributor margin and shortens lead times. Each system is factory-tested, documented and delivered with a 10-year battery warranty.

Before ordering, model the total landed cost including freight and duty with our BESS import guide, and review how projects are commissioned in our 100kW/215kWh Sudan microgrid case study.

Solar-plus-storage is now the cheapest source of new generation in most markets. The U.S. Department of Energy's Solar Energy Technologies Office tracks the cost curve behind this shift, and it is falling system prices that make a 50kW BESS affordable today.
