It specifies wire gauges, voltage requirements, and emphasizes connecting the PE protective conductor to ground first.

3.2.1 Conectarea panoului solar

• Connect solar panels in series to achieve a total open circuit voltage between 120V and 450V DC. The starting voltage trebuie să fie mai mare de 150V.
• A minimum of 4-6 solar panels are typically needed to initiate inverter operation, depending on individual panel specifications.
• Ensure the maximum PV input power does not exceed 4000W and the maximum input current is 13A.
• Use 12AWG wire for PV connections.

3.2.2 Conectarea bateriei

• Connect a 24V battery bank (lithium or lead-acid) to the battery terminals.
• A recommended battery capacity is 200Ah.
• Use 2AWG wire for battery connections.
