Questions you probably have

Do I really not need solar panels?

Really. Ohmie is specifically designed for homes without solar. The battery pays for itself through tariff arbitrage - charging when electricity is cheap (overnight) and discharging when it's expensive (daytime). No panels required.

Can my regular electrician install this?

Yes. You choose who and pay them direct. No approved installer network, no markup. We provide a step-by-step guide and do a quick video call with your electrician to commission the system. Phone support if they get stuck.

What tariff do I need?

Any time-of-use tariff with cheap overnight rates works. Octopus Intelligent Go (7p overnight) is the most popular. Economy 7 works too. The battery works for any tariff out of the box.

How long until it pays for itself?

Typically 3-4 years for a battery-only setup. After that, you're saving £600-800+ per year, every year. The battery is warrantied for 10 years and designed to last 15+.

What's included in the bundle?

Everything: battery unit, compatible inverter, all cables (DC, AC, and communication), mounting brackets, installation guide, and our quick-start customer guide. No hunting for parts or compatibility research needed.

Do I need to download an app?

We're designing Ohmie to be true set-and-forget. Pre-configured for your tariff, with status visible on the built-in display. No app required for everyday use.

Why I started Ohmie

Hi, I'm James. When I looked into home batteries, I found a minefield. Dozens of brands, confusing specs, compatibility questions, and hours of research just to figure out what would actually work for my house. I just wanted something that works - without becoming a battery expert first.

So I'm building Ohmie: one bundle, guaranteed compatible, pre-configured for UK tariffs, and installable by any qualified electrician. No endless research. No guesswork. Just a box that saves you money from day one.
