5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your SRNE solar inverter. This device is an indoor product and is forbidden for outdoor use.
5.1 Basic System Introduction
The inverter is a key component in a complete solar power system. The system typically includes:
- PV module: Converts light energy into direct current (DC) to charge the battery or directly invert it into alternating current (AC) to power loads.
- Mains or generator: Connected at the AC input, it can supply power to the load and charge the battery simultaneously. If no mains power or generator is connected, the system operates normally, with power supplied by the battery and PV modules.
- Battery: Ensures normal power consumption of the system load in case of insufficient solar energy or mains supply.
- Household load: Can be connected to various household and office loads, including AC loads such as refrigerators, lamps, televisions, fans, air conditioners, etc.
- Inverter: The energy conversion device of the whole system.
The specific system wiring mode is determined by the actual application scenario. Always ensure all connections are secure and follow local electrical codes.
