Frequently Asked Questions (FAQ)

The 5kW is the maximum power output, while runtime is determined by battery capacity (kWh) and the average load. Your system capacity is 26.114kWh, so at a 2kW average load it may last roughly 10–12 hours, while at 5kW it may last around 4–5 hours. Actual runtime varies with inverter efficiency, temperature, and surge loads.

For many homes, a 5kW system can power essential loads, but whether it “runs the whole house” depends on peak demand and how many large loads (AC, ovens, pumps) are used simultaneously. Many projects use priority circuits to guarantee critical loads remain powered during outages. For higher power needs, consider OEM/ODM customization.

If you mean a 5kW PV array, panel count ≈ 5,000W ÷ panel wattage. With 400W panels that’s about 13 panels; with 550W panels about 9–10 panels. Roof space, shading, orientation, and local interconnection rules will influence final design.

Cost varies widely by market, on-grid vs hybrid design, equipment brand level, and installation complexity. A 5kW PV-only system and a 5kW PV + storage system are priced very differently because batteries and backup hardware add major cost. The most accurate method is a configuration quote based on PV size, battery kWh (e.g., 25kWh), certification requirements, and installation scope.

Daily production depends on peak sun hours and system losses. As a rough estimate: 5kW × 4–6 sun hours = ~20–30 kWh/day before site-specific adjustments. Shading, tilt/azimuth, and temperature can reduce real output.

Runtime depends on energy capacity (kWh) and household load. Many homes average 1–3kW overnight (higher with AC), so a ~20kWh battery might cover much of the evening and nighttime. For heavy cooling loads, runtime can be significantly shorter.

Panels increase energy generation, while batteries increase nighttime usability and backup resilience. If your batteries rarely reach full charge, add more panels first. If your batteries fill early and you still buy grid power at night, add more battery capacity.

In most cases, yes—30kW is a high residential power level. Whether it’s needed depends on simultaneous loads, AC tonnage, and whether you run electric cooking, water heating, or EV charging at the same time. Proper load calculations are the best way to confirm.

On-grid PV cost depends on local labor, equipment, and permitting. A hybrid system with storage and backup capability costs more due to batteries, transfer hardware, and additional protection components. For accurate pricing, projects are usually quoted by PV kW + battery kWh + compliance requirements.

The 40/80 rule is a longevity guideline: keeping batteries between about 40% and 80% SOC for routine daily use can reduce long-term degradation. LiFePO4 is durable, but avoiding long periods at 100% (especially in heat) can still help maximize lifespan. Many users reserve full charge for outage readiness.

Batteries store energy; they don’t create it. They can reduce costs by shifting solar energy to nighttime use, avoiding peak rates, or improving self-consumption where export rates are low. Whether batteries save money depends on your rate plan, usage profile, and system cost.

Electric bills are based on kWh, but 240V can reduce current and wiring losses for high-power loads. Many large appliances operate more efficiently or more practically at higher voltage due to lower current requirements. Final cost still depends on appliance efficiency and usage time.

Tax treatment depends on country and local rules. In some cases, medically necessary backup power or certain efficiency upgrades may qualify, but there is no universal rule. For accurate guidance, consult local tax authority resources or a qualified tax professional.

It depends on simultaneous loads and surge demands, not just square footage. Many 22kW generators can cover most household circuits if load management is used, but multiple AC units, electric cooking, and electric water heating can push demand higher. Load calculations provide the most accurate answer.
