View product →Things to consider
What to check before buying.
01Compare complete systems
A battery-only price is not comparable with an installed hybrid system. Ask for an itemised battery, inverter, gateway and switchboard scope.
02Allow for site work
Long cable runs, backup circuits, phase equipment and switchboard upgrades can move a real quote beyond the planning range.
03Read the full warranty
Check throughput, retained capacity, labour and authorised-installer conditions instead of counting years only.
