Electrical safety comes first

Working on electrical systems can cause electric shock, fire, serious injury and death. Every installation, modification or repair involving mains voltage, battery banks, inverters or fixed wiring must be carried out or verified by a licensed electrician in compliance with the Philippine Electrical Code.

Estimates, not engineering designs

The calculators on this site apply standard formulas and widely used rules of thumb to the numbers you enter. They cannot see your actual equipment, your ambient temperature, the age and condition of your batteries, how your cables are routed and bundled, or the quality of your components. Results should be treated as a starting point for a conversation with a qualified professional — not as a specification to build from.

Specific limitations you should know

Cable sizing here assumes copper conductors at normal ambient temperature with ordinary installation conditions. Bundled cables, hot roof spaces, long conduit runs and high ambient temperatures all require derating that this tool does not apply.
Fuse and breaker sizing is calculated from continuous load with a standard safety margin. Real circuits may need different protection depending on device characteristics, coordination with upstream protection and code requirements.
Battery runtime assumes a healthy battery at moderate temperature. Age, heat and previous deep discharges all reduce real capacity, often substantially.
Solar output uses peak sun hour averages. Actual generation varies daily with weather, shading, panel orientation, soiling and season.
Financial figures depend on assumptions about electricity rates, rate increases and equipment life. They exclude maintenance, inverter or battery replacement, financing costs and taxes. They are not financial advice or a guaranteed return.

The AI assistant

The AI assistant is a language model. It can be confidently wrong, misread your situation, or produce figures that look plausible but are not correct. Treat its replies as you would a helpful but unverified opinion, and check anything that carries cost or risk. Never rely on it for installation instructions.
