Product Overview
The Solis Mini 700-4G converts DC power from the solar array into 230V/50Hz AC power for use in the property or export to the grid. Its 60V start-up threshold means the inverter begins operating at the first usable light of the day and continues generating at low irradiance levels when higher start-up threshold inverters remain inactive.
The dynamic MPPT tracker continuously identifies the maximum power point of the connected array, achieving above 99% MPP output regardless of panel make, cell count, or configuration. The wide 0 to 8A current input range makes it compatible with modern higher-efficiency panel designs.
QNS anti-islanding protection is included as standard, ensuring the inverter disconnects automatically from the grid during a power failure.

Installation and Safety Notes
Must be installed by a qualified electrician or MCS-accredited solar installer. G98 notification to the DNO is required before grid connection in the UK. All DC isolators, AC protection, and earthing must comply with BS 7671 and the applicable MCS installation standard. Do not attempt DIY connection of grid-tied equipment.
