Straight answers, before you ever talk to sales.

Take your daily energy use in kWh, divide by 0.85 to account for depth of discharge, then round up to the nearest standard battery size — usually 5.12, 10.24 or 15.36 kWh. Most three-bedroom homes land on one 10.24 kWh battery.

Choose an inverter by matching its kVA rating to your peak load plus a safety margin — not your total energy use. For most homes, that means a 3.5–5kVA hybrid inverter. Larger homes and small businesses typically need 8–10kVA.

A generator is cheaper on day one but fuel, servicing and replacement make it cost more than solar + battery within 3–5 years — before counting noise, fumes and late-night refills. Here's the comparison with real numbers.

Most three-bedroom homes need a 5kW solar array to fully recharge a day's typical use. The real number depends on your daily energy consumption and average sun hours in your location — not the size of your house or roof.

A 5kVA inverter runs roughly 5,000 watts at once — comfortably covering a fridge, TV, lights, fans, washing machine and small AC together, as long as they don't all start in the same instant. Paired with 10.24kWh battery, it's our most common setup.

Lithium batteries store energy by moving ions between electrodes — no moving parts, no fluid to top up, far less capacity loss than lead-acid. The LiFePO₄ chemistry used in solar systems is chosen specifically for safety and long cycle life.

Divide usable battery capacity (kWh) by actual running load (kW) to get runtime in hours. A 10.24kWh battery at 90% DoD on a 1kW load lasts roughly 9 hours — but the real number depends entirely on what's switched on, not the box.

A well-installed solar system needs far less upkeep than a generator — mostly occasional panel cleaning, a yearly professional inspection, and keeping an eye on the monitoring dashboard. No oil changes and no fuel to buy.

Most households don't remove their generator on day one — they shift it from daily necessity to rare backup by covering normal loads with solar + battery first, in realistic stages that don't require betting everything upfront.

A solar system carries several separate warranties — panels, batteries, inverters and installation workmanship are each covered differently, by different parties, for different lengths of time. Knowing which is which makes claims smooth instead of frustrating.
