Batteries

Pick the battery that fits your evening, not the biggest one in the shop.

Named units are real models. Four size guides show a typical price, dated. Where a unit has no price yet, ask us.

Not sure what size you need? Answer two questions on the home page and we will tell you.

Where these prices come from

Rows without a brand name are Philippine retail price bands for that whole class, taken from a market snapshot and re-checked before every release — not one shop's listing. Rows with a brand name are real units Brownout can source; where no Philippine retail price exists yet, the row says so and sends you to ask rather than showing a made-up number. Petrol generators appear for comparison only — we do not recommend or list them.

Small · a battery box you plug in, 512 Wh – 1 kWh

₱28,000–65,000. Plug-in, no installation. Runs LED lights, the router, a fan and a laptop for an evening; a mini-fridge for a few hours. Recharges from the wall in a few hours, or from a portable solar panel sold separately.

Medium · a battery box you plug in, 1–2 kWh and up

₱45,000–90,000+. Still plug-in. A full-size fridge for a day, everything the small one does for longer, power tools. Most units in this class take 200–400 W of portable solar.

Large · a battery on the wall, 5 kWh, with a hybrid inverter

₱160,000–240,000 before labour (5.12 kWh LFP module ₱84k–126k + 5 kW hybrid inverter ₱76k–114k). Switches over in seconds when the grid drops; lights, fans, Wi-Fi and fridge for a whole evening. Needs a licensed electrician. Solar-ready.

Largest · a battery on the wall, 10–15 kWh

₱135,000–300,000 for the battery alone (10.24 kWh ₱135k–203k; 15 kWh class ₱200k–300k, extrapolated). Adds a small aircon for a few hours, or the essentials all night. Solar-ready.

For comparison, not for sale — a petrol generator: cheap to buy, expensive every hour it runs, loud, and it cannot sit inside the house. We show it so the year-one arithmetic is honest; we do not list or rank them.

The sizing calculator

Indicative estimate, not a quote. Tick what you want to keep on, set hours per day, and the safety-margin math is editable — every assumption is visible.

ApplianceQtyHrs/dayWatts
Show the math — view & edit every assumption
Headroom over the raw watt-hour sum, for inrush current & inverter inefficiency. ⚠ rule of thumb.
The load should only use this share of the battery's rated (nominal) Wh — LFP batteries are typically safe to ~90% depth of discharge. ⚠ rule of thumb.
Your result

Add solar later

Every unit on this page either has a built-in solar input or pairs with a hybrid inverter, so you don't have to buy panels on day one — the battery keeps the lights on tonight, and solar can bring the running cost down whenever you're ready. See the solar savings calculator.
