Frequently Asked 6.6kW Questions

Western Power doesn’t allow single-phase solar inverter capacity greater than 5kW output. Synergy excludes solar inverter capacities which exceed 5kW output capacity from the Distributed Energy Buyback Scheme.

The great news, most leading inverter brands state that their inverters can be overloaded by up to 50%.

The Clean Energy Regulator has had its say on this topic and capped the oversizing of solar inverters to 33%.

Therefore, 5kW Inverter capacity x 1.33 = 6.6kW of solar panels.

Oversizing solar inverters explained in even more glorious detail >

This all depends on you. A 6.6kW solar energy system with a 5kW inverter will generate an annual average 30units (kWh) per day.
However, each bill and usage pattern is different. So much so, it’s as unique as your finger print.
Perth Solar Warehouse Sales Support can provide detailed bill reduction estimates based on your past energy usage patterns. And, the more past power bills you provide the more accurate your bill reduction estimate is likely to be.


It’s all about battery selection. For example, if the only battery you want to install in the future is a Tesla Powerwall 2 (AC-Coupled), then selecting any standard inverter will work.

However, should your preference be an LG Chem RESU HV (DC-Coupled) then a compatible solution would require a hybrid solar and battery inverter such as the Huawei SUN2000-L1 or SolarEdge HD-Wave/ Storedge inverter. 

Unless stated, all 6.6kW solar packages come standard with WiFi connected production monitoring and service alerts only.

To include energy consumption monitoring, an addition monitoring device is required at the main switchboard.

Ask Perth Solar Warehouse Sales Support prior to your 6.6kW solar installation for exceptionally discounted prices on energy consumption meters.
