Backup Power & Inverter Installation — Beat Dumsor
Tired of dumsor? Electricals Ghana sizes, installs and repairs inverter + battery backup that keeps your lights, fans, fridge and Wi-Fi on when ECG goes off — correct sizing, an automatic or manual changeover, and an honest before-work price. Energy-Commission-licensed, since 1987.
Dumsor does not have to mean a dark house, a spoiled fridge and a dead router. Electricals Ghana sizes, installs and repairs inverter + battery backup that keeps the things you need running when ECG goes off — Energy-Commission-licensed electricians, since 1987. Call +233 23 063 0022 and tell us what must stay on; we size it honestly and give you a price before we start.
Backup That Actually Lasts Through an Outage
The mistake most people make is buying the box first. A backup system is only as good as the sizing behind it: the inverter has to handle what you switch on, and the battery has to hold enough to last the hours you need. We work the other way round — from your real load and your target runtime — so what you buy actually carries you through dumsor instead of cutting out when the fridge kicks in.
What We Do
Size It From Your Real Load
We list what must stay on — lights, fans, the fridge, the router, a TV, phone charging — add the running watts and the start-up surge, and decide the inverter and battery from that. A number, not a guess.
Choose Inverter & Battery Honestly
A pure-sine-wave inverter for anything with a motor or compressor (fridge, pump), and a battery bank sized to your hours — lithium for long life and deeper discharge, or tubular for a lower up-front figure. We tell you what each runs for and what it costs to own.
Wire the Changeover Safely
A manual changeover switch or an automatic transfer switch (ATS) so the inverter feeds your circuits when ECG drops and isolates cleanly when it returns. This must be done by a licensed electrician — a wrong changeover back-feeds the line and is dangerous.
Repair “Inverter Not Charging” & Other Faults
The most common call: the system stops charging. We test the charger, battery health and wiring to find the real cause — a faulty charge circuit, a dead battery, a loose terminal, a blown fuse, a charge-controller fault — instead of replacing parts at random.
What Runs, and For How Long
Runtime is load times battery, nothing magic. The honest answer is always sized to your house, but the shape is this:
| What you run | Draw | Typical effect on runtime |
|---|---|---|
| Lights, router, phone charging | Low | Many hours on a modest battery |
| Fans + TV added | Moderate | Several hours, sized to the bank |
| Fridge / freezer added | High (surge on start-up) | Needs pure-sine + a larger battery |
| Water pump / heavy motor | High surge | Sized carefully; pure-sine only |
(Indicative shape only. Actual runtime is calculated from your measured load and the battery capacity — confirmed on a quick on-site look, not promised down the phone.)
Manual vs Automatic Changeover
| Changeover | What it does | Best for |
|---|---|---|
| Manual changeover switch | You flip it by hand when power goes | Lower-priced, reliable, simple homes |
| Automatic transfer switch (ATS) | Switches over by itself in a second | Fridges, freezers, anyone not home to switch |
Both are correct; both must be wired by a licensed electrician so the inverter never back-feeds the ECG supply.
What It Costs — Honestly
The unit — an all-in-one inverter-plus-battery package — is sold at retail, so that figure is on the shelf. The installed price depends on your load, the battery size for the hours you want, and the changeover. As one indicative reference, generator-changeover install labour runs around “GH₵300–600”. We separate the unit from the labour, size honestly from your real load, and give you a firm before-work price from a quick on-site look — never a fabricated flat rate.

Frequently Asked Questions
How long will an inverter run my house during dumsor? It depends on the load and the battery size. Lights, fans, a router and charging run for many hours on a modest battery; add a fridge and the draw rises sharply. We size from your real load and target hours and tell you plainly what it will run, and for how long, before you spend anything.
My inverter is not charging — can you fix it? Yes — it is one of the most common faults we attend. The cause is usually a faulty charge circuit, a dead battery, a loose terminal, a blown fuse, or a charge-controller fault. We test the charger, battery health and wiring to find the real cause, and tell you whether it is a repair or end-of-life battery.
Do I need an automatic changeover or a manual switch? Both work — a manual switch is lower-priced and you flip it by hand; an ATS switches over by itself, which matters for a fridge or when nobody is home. Either way it must be wired by a licensed electrician so the inverter never back-feeds the ECG line.
How much does an inverter and battery system cost? The unit sits at retail; the installed price depends on your load, battery size and changeover. As an indicative reference, generator-changeover install labour runs around GH₵300–600. We separate unit from labour and give a firm before-work price from a quick on-site look — never a fabricated flat rate.
