PowerAll is an authorised distributor for Solis, the world’s third-largest PV inverter manufacturer, and an authorised partner for Huawei Smart PV. We size the inverter to your loads, supply phase and battery, and commission it on site.
Our engineers’ short guide. We confirm the right choice for your site during the free assessment.
Single or three phase?
Match the inverter to your KPLC supply. Most homes are single phase; larger homes, offices and factories are usually three phase. Three-phase hybrid inverters handle unbalanced loads across phases.
Low or high voltage battery?
Low-voltage (48V) inverters pair with wall or rack lithium batteries and suit homes. High-voltage models pair with stacked HV batteries and are more efficient at commercial scale.
Backup and generators
Hybrid inverters switch to battery in under 4 ms during an outage, and many Solis models can start and manage a generator to extend backup.
Size the inverter to your peak simultaneous load — the appliances that run at the same time — with headroom for motor start-up. A typical three-bedroom home with a fridge, pump and electronics often needs 5–8 kW.
Can I add batteries later?
Yes, if you start with a hybrid inverter. It can run grid-tied today and accept a compatible lithium battery later without replacing the inverter.
