An 800W dual-MPPT microinverter for compatible residential solar systems in the UK.
The LS-800Mi is a LONGSHEE-manufactured, LONGSHEE-branded 800W microinverter supplied through Wrenstead Energy.
Featuring two independent MPPT inputs, 230V AC output, Wi-Fi communication and an IP67-rated enclosure, it converts compatible DC electrical input into AC electricity for a suitable grid-connected solar installation.
The package includes the microinverter and a 5-metre AC connection cable.
The LS-800Mi is also included in the Wrenstead Solar + Store 2 system.
800W Microinverter for UK Solar Systems
The LS-800Mi provides up to 800W rated AC output with two independent MPPT inputs.
Its dual-MPPT design supports independent maximum power point tracking for compatible connected solar inputs.
Before ordering, solar panel voltage, current, available connection arrangements and UK electrical requirements should be checked against the microinverter specifications.
This product is a grid-connected microinverter, not a standalone home battery, off-grid inverter or backup power supply.
