Frequently Asked 10kW Questions

Western Power may restrict inverter capacity in certain network locations to no more than 8kW output capacity.

As solar panels rarely reach peak rated power, certain solar inverter manufacturers state that their inverters can be overloaded by up to 50%.

However, the Clean Energy Regulator has had their say on this topic and capped oversizing to 33%.

Therefore, 8kW Inverter capacity x 1.33 = 10.64kW of solar panels.

Oversizing solar inverters explained in even more glorious detail >

This all depends on you. A 10kW solar energy system with an 8kW inverter will generate an annual average 45-units (kWh) per day.
However, each bill and usage pattern is different. In fact, 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. Quite simply, the more past power bills you provide the more accurate our data.


It’s all about battery selection. For example, if the only battery you want to install on your 10kW solar energy system in the future is a Tesla Powerwall 2 (AC-Coupled), then selecting any standard inverter will work.

However, should your preference be a BYD HVM or Soluna HV (DC-Coupled) then a compatible solution would require a hybrid solar and battery inverter such as the Goodwe ET inverter range. 

Unless stated, all 10kW solar packages come standard with WiFi connected production monitoring and service alerts only.

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

Ask Perth Solar Warehouse Sales Support prior to your 10kW solar installation for exceptionally discounted prices on energy consumption meters.

Approved Perth and Bunbury region customers (STC Zone 3) can enjoy a $5154 subsidy when installing 10.3kW of solar panels on an 8kW inverter.

Based on 143 claimable Small Technology Certificates, with a system utilising 28 x 370W solar panels and a $36 STC market valuation 

143 STC’s x $36 market value = $5154 subsidy.

For your convenience, the Perth Solar Warehouse 10kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by Perth Solar Warehouse after installation).
