Glossary

Maximum charge current

The maximum amount of direct current in amperes that the inverter can convert. If the solar panel produces a current exceeding this value, the inverter simply does not use it. This is often justified when connecting an inverter to high-power solar panels - the maximum input current of the inverter is reduced to acceptable values so that moderate-sized wires can be used to transmit energy.

Display

The presence of its own display provides more visual control of the device’s operation. Various operating characteristics can be displayed on the screen: current electricity generation, load level, voltage and frequency in the network, operating mode, battery charge, etc. Inverters are equipped with both simple monochrome displays and full-fledged color panels for visual visualization of parameters.
