KSTAR Home Series technology

Integrated hybrid power, built around modular storage.

The Home Series combines a single-phase hybrid inverter, intelligent charging and 5.12 kWh LFP battery modules in a compact architecture. GreenPower selects the inverter capacity first, then the storage and solar array.

Single-phase hybrid inverter platform

Three core inverter classes.

Choose power capacity for the loads that must run together. Battery modules and PV capacity are then matched to each appliance’s daily operating hours and the charging conditions.

Before you invest

Straight answers to the questions homeowners ask most.

Use these answers for planning. GreenPower confirms performance, scope and commercial terms in the final design and quotation.

01How do I know which KSTAR system my home needs?+

Size the system from the appliances that must run together, their starting demand and the daily operating hours required for each appliance—not from bedroom count alone. Start with the load calculator, then GreenPower verifies the load schedule, electrical phase and site conditions before recommending the inverter, battery and solar array.

02How long will the battery power my home during an outage?+

Runtime depends on usable battery energy and the appliances operating. Lights, fans, a TV, router and refrigerator consume far less than air conditioners, pumps or heating appliances. The calculator lets you set hours per day beside every appliance, totals the daily energy requirement and then allows for conversion losses.

03Can a KSTAR system power air conditioners?+

Yes, provided the design accounts for AC type, quantity, running power, compressor starting demand and required operating time. An inverter may have enough power to start an AC but still need more battery capacity for several hours of operation. Add every AC separately in the calculator.

04Will the system power every appliance in the house?+

It can be designed for essential circuits or broader whole-home coverage. Electric cookers, water heaters, irons, pumps, microwaves and multiple ACs raise inverter and battery requirements quickly. Separating essential and non-essential circuits helps preserve runtime during long outages.

05Can I buy the system without new solar panels?+

Yes. GreenPower offers storage-only configurations that can charge from available grid or generator supply. This may suit a home that already has solar panels or mainly needs quiet backup. The charging source, cable capacity and protection arrangement still require verification.

06Can it work with the grid and my generator?+

The system can be integrated into a properly designed hybrid arrangement, subject to compatibility and electrical-protection checks. GreenPower determines the charging priority and changeover logic so the battery, grid, generator and solar sources operate correctly together.

07What happens during cloudy or rainy periods?+

Solar production falls when irradiation is low. A correctly sized system balances the solar array, battery reserve and available grid or generator charging. The final design should reflect the loads you must protect and the autonomy you require during poor weather.

08Can I expand the battery or inverter later?+

Expansion may be possible when the original battery model, inverter architecture and protection design support it. Tell GreenPower about future ACs, pumps, building extensions or additional apartments now so the first design does not create avoidable upgrade costs.

09What happens from enquiry to installation?+

GreenPower reviews your calculated load and appliance-by-appliance operating schedule, checks the site where necessary and issues a proposal. After approval, the team supplies, installs, tests and commissions the system, explains its operation and confirms the protected circuits.

10How quickly can the system be delivered and installed?+

The supplied schedules use a planning lead time of 1–2 weeks. Actual timing depends on stock, location, roof or mounting work, system size and site readiness. GreenPower confirms the delivery and installation programme in the formal quotation.

11What warranty and after-sales support are included?+

The KSTAR 2024-V1 brochure states a 10-year performance warranty for the H-PACK-5.1 battery, while GreenPower’s supplied commercial schedule states a five-year equipment warranty for the KSTAR inverter and lithium battery. These are different warranty descriptions. The signed quotation and product warranty documents will confirm the coverage, performance conditions, exclusions and claim process for your installation.

12Are the prices on this website final?+

No. They are indicative installed estimates derived from the supplied 2026 schedules. Final pricing depends on current equipment costs, exchange rates, location, mounting method, cable distances, protection requirements and the verified load. The binding price appears in GreenPower’s formal quotation.
