Our opinion
The buying view.
EDITORIAL OPINION - BASED ON THE CITED RESEARCH
“EP2000 fills a real high-output gap for three-phase homes. It is excessive for many households, so the decision should be driven by measured concurrent loads, winter recharge and a complete gross-cost proposal rather than the 20 kW headline.”
Best suited to
Large three-phase homes needing substantially more than 10 kW of inverter output
What stands out
Current Australian packages combine roughly 19.91–46.44 kWh CEC-listed usable capacity with a CEC-listed 20 kW three-phase inverter
03
Cons and watch-outs
What to check before buying.
These are configuration trade-offs and questions to verify, not claims that the product is defective.
Its minimum current package is already a large system, which can be unnecessary for a modest overnight load or limited winter solar production.
Advertised installed prices can be after rebates and limited to standard metro installations; backup protection and switchboard work may add materially to the final price.
Ask for these points to be answered against the exact model numbers and installed configuration in your quote.
