❓ Dr. Steve Thomas questions the WA government on the Residential Battery Scheme, specifically regarding AC-coupled systems, inverter costs, and rollout delays. The answer refers to a previous question.

I refer to the Government’s requirements and compliance costs for the connection of alternating current (AC) coupled households proposing to install batteries to the South West Interconnected System (SWIS) under the Government’s floundering WA Residential Battery Scheme, and I ask:(a) what percentage of residential AC supply recipients in the SWIS who want to install a new solar panel and battery system are installing a hybrid inverter;(b) what is the average cost of an inverter for a battery installed on an AC residential system and the average cost of a hybrid converter;(c) to what extent has the need for inverter upgrades for AC supplied residences delayed the roll out of the WA Residential Battery Scheme; and(d) given the scheme only paid for 4,605 battery rebates in its first four and a half months or about 1,000 a month, how long will it take to deliver all 100,000 rebates on offer?
