The battery module supplied is the \u003cstrong\u003eSigenStor BAT 8.0\u003c\/strong\u003e, which has a nominal capacity of 8.06 kWh (7.8 kWh usable). Sigenergy and some distributors refer to this as a \"9.0 kWh\" battery in product titles — this likely reflects marketing rounding or naming alignment with a newer BAT 9.0 module (9.04 kWh) introduced for other markets. The part number BAT-8.0 in the SKU is the definitive reference. The actual usable storage delivered is 7.8 kWh from a single module.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sgs-faq-item\"\u003e\n    \u003ch3\u003eIs the 6.0kW inverter right for my home?\u003c\/h3\u003e\n    \u003cp\u003eThe EC 6.0 SP is best suited to homes with larger solar arrays (typically 4kW–12kW), higher daytime consumption, or where a single EV charger may be running simultaneously with household loads. For a typical UK home with a 3–4kW solar system, the EC 3.6 SP is often sufficient and more cost-effective. The 6.0kW rating means more solar power can be converted and more stored energy can be discharged simultaneously — notably, the backup peak output of 9,000W (vs 5,520W for the 3.6 SP) also provides more headroom for running large appliances during a power cut.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sgs-faq-item\"\u003e\n    \u003ch3\u003eCan I add more batteries to this system later?\u003c\/h3\u003e\n    \u003cp\u003eYes — this is one of SigenStor's core strengths. The EC 6.0 SP supports 1 to 6 battery modules, so you can add up to 5 more BAT modules over time, reaching up to 48.36 kWh with BAT 8.0 modules. No inverter changes are required. Modules can also be mixed (BAT 5.0, 6.0, and 8.0), with the per-module battery optimiser managing any differences in age or capacity. Each additional module simply stacks beneath the existing stack.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"sgs-faq-item\"\u003e\n    \u003ch3\u003eDoes this system qualify for any UK incentives?\u003c\/h3\u003e\n    \u003cp\u003eBattery storage (when installed alongside or connected to solar panels) qualifies for 0% VAT under the UK's Energy Saving Materials scheme.
