What is a "Complete Off-Grid Solar System + Battery"?

When we talk about "off-grid solar systems," it's not just about solar panels. A complete system includes at least:

* Solar photovoltaic panels (PV panels) – Used to capture sunlight and generate direct current (DC).

* Battery (Energy Storage) – Stores the electricity generated during the day for use at night or on cloudy days.

* Inverter (Inverter/Hybrid Inverter/Off-grid Inverter) – Converts the DC output from the battery/DC converter into alternating current (AC) for use with ordinary household appliances.

* BMS (Battery Management System) and System Control Unit – Monitors battery status, provides safety protection, and prevents overcharging/over-discharging/abnormal temperature.

* Installation Accessories and System Integration – Brackets, cables, connectors, and overall system design and installation planning.

ONESUN's "complete solution" covers all of the above. Whether for small residences, rural homes, remote mountain huts, mobile homes, or off-grid villas/farms/small businesses, its "PV + Energy Storage + Inverter + System Integration" combination can be quickly deployed and operate stably.
