\"Sigenenergy<\/p>\n

There was an eagerly-awaited addition to Synergy’s Supported Solutions List for Western Australia’s home battery rebate in the last few days. But some other notable players are still missing in action.<\/p>\n

Who Made Synergy’s Supported Solutions List?<\/h2>\n

On Friday afternoon (August 22), various Sigenergy SigenStor<\/a> battery systems, hybrid inverter and energy controller modules were finally added<\/a> to Synergy’s list. This means the Sigenergy equipment noted is now eligible under Western Australia’s Residential Battery Scheme.<\/p>\n

While Sigenergy is not the Messiah<\/a>, the SigenStor is taking some of the limelight previously occupied by another popular brand led by an interesting CEO<\/a>. Tesla is still conspicuously missing from the list.<\/p>\n

\"So<\/p>\n

The delay in Sigenergy’s listing was causing some angst in the industry, and among households keen to get a SigenStor installed.<\/p>\n

Some Rebate Synergy, But Hurdles A-Plenti<\/h2>\n

The national solar battery rebate<\/a>, currently worth around $330 per usable kilowatt-hour (kW) usable capacity, requires batteries be on the Clean Energy Council’s Approved Batteries List<\/a> and the system to be Virtual Power Plant (VPP)<\/a> *capable*.<\/p>\n

But they are taking things a couple of steps further out west in the Cook Government’s WA Residential Battery Scheme<\/a>, which like the national scheme also kicked off on July 11<\/a><\/sup>.<\/p>\n

In the Synergy area, which includes Perth and WA’s south-west, hybrid inverters<\/a> and ‘all-in-one’ battery systems with inbuilt inverters must also be on Synergy\u2019s supported solutions list<\/a> for state rebate eligibility2<\/a><\/sup>. In Synergy’s service area, the state rebate is worth $130 per kilowatt-hour of usable battery capacity up to 10 kWh \u2014 so, a maximum rebate of $1,300.<\/p>\n

In other areas of the state, solutions also need to be on Horizon Power\u2019s list<\/a>. In Horizon’s service area3<\/a><\/sup>, the rebate is worth $380 per kilowatt-hour of usable battery capacity up to 10 kWh \u2014 a maximum rebate of $3,800. Sigenergy hasn’t popped up on that list at the time of writing.<\/p>\n

Furthermore, the WA subsidy (which can be ‘stacked’ with the national rebate) rules require connection to a VPP<\/a>.<\/p>\n

Among other cogs in this complex machine is Plenti, a ‘Buy Now, Pay Later” (BNPL) provider<\/a>. Plenti is the scheme’s administrator and financier; providing optional interest-free loans of up to $10,000 for home battery systems. The firm also plays a role in *who* can install battery systems. As well as installers requiring SAA (Solar Accreditation Australia) accreditation, participating solar businesses must also be approved by Plenti.<\/p>\n

Other Manufacturers On Synergy’s ‘Approved’ List<\/h2>\n

Technology providers are required to offer solutions meeting Synergy\u2019s DER Functionality Requirements<\/a> and Utility Interconnection Handbook<\/a>, and verified as such.<\/p>\n

Sigenergy was the only new addition on August 22 to the Synergy list, which had previously last been updated on August 8. Selected battery systems and inverter equipment from the following brands is currently supported.<\/p>\n
