Sized to your actual backup need, wired on a separate load line.
An inverter that runs your whole flat will run it badly. We calculate the backup load you genuinely need, size the VA and battery to match, and wire a separate backup line so essential circuits stay live and the geyser never drains your battery by accident.
The most common inverter mistake in Surat homes is not buying the wrong brand — it is wiring the inverter output back into the whole house. It feels generous. In practice it means that during a power cut, the geyser someone forgot to switch off, the microwave, the iron and every air-conditioner are all connected to a battery designed to run fans and lights. The inverter overloads and shuts down, or the battery is flattened in twenty minutes and its life is shortened permanently.
The right approach is a dedicated backup distribution line. We identify the circuits that genuinely matter during an outage — fans, lights, television, router, refrigerator and a few charging sockets — and wire them onto a separate way from the inverter output, distinguished physically so that nobody can plug a heavy load into them by mistake. Everything else stays on mains only. The result is an inverter that runs for hours instead of minutes and a battery that lasts its full design life.
Sizing follows from that. We total the backup load in watts, apply the inverter's power factor, add a startup margin for the refrigerator compressor, and arrive at a VA rating — usually 900 VA for a small flat running fans and lights, 1100 to 1500 VA for a 2 or 3 BHK including a fridge, and 2000 VA and above where a bungalow or a small office is involved. Battery capacity comes from the hours of backup you actually want, not from whatever the showroom is discounting.
Battery choice matters more than most buyers realise. A tall tubular lead-acid battery remains the best value for Surat's climate and typical outage pattern, tolerating heat and deep discharge better than flat-plate alternatives, and lasting four to five years with routine topping up. Lithium systems cost substantially more upfront but need no maintenance, occupy a third of the space and last eight to ten years — worth it in a small apartment where the trolley is in a living area. We will tell you honestly which suits your situation.
Installation details decide safety. Batteries are placed on a proper trolley or ventilated stand, never in a sealed cupboard — lead-acid cells vent hydrogen and need airflow. Cable between battery and inverter is short and heavy, because voltage drop on a long thin DC run wastes a surprising fraction of your stored energy. Terminals are greased against Surat's coastal humidity. The inverter gets its own MCB on the mains input. And we label everything, so the next electrician who opens that cupboard understands the system immediately.
The difference between a job that lasts and one you will be calling about again is almost always in the details below.
We total your real backup requirement in watts and size the VA and Ah from that, not from a showroom recommendation.
Essential circuits only. A geyser or an AC can never be accidentally connected to your battery and flatten it.
Correct DC cable sizing, short runs, proper ventilation and greased terminals typically add a year or more to battery life.
We explain the real cost per year of each for your usage pattern and let you choose, without steering you to a margin.
We simulate an outage under your actual backup load and measure how long it holds, so you know what you have bought.
Luminous, Microtek, Exide, Amaron, V-Guard, Su-Kam — we install and wire whatever you buy, or supply it for you.
Every step is the same whether the job is worth ₹400 or ₹95,000.
We list what must stay live during an outage, total the wattage and recommend a VA and Ah combination with expected runtime.
Inverter and battery positions are chosen for ventilation, cable length, noise and access for future maintenance.
A separate distribution way and dedicated circuits are run to the essential points, with distinct socket identification.
Heavy short-run DC cable with lugged terminals, mains input on its own MCB, and full polarity verification before energising.
Mains is cut deliberately, changeover time is checked, and backup duration is measured under your real load.
Water-topping schedule, terminal-cleaning interval and warning signs explained, with everything labelled at the unit.

Prices exclude civil repair and repainting where wall chasing is involved. Materials are charged at cost with original bills handed over, and there is no emergency markup on parts at any hour.
They surveyed the flat properly before quoting — actually walked around listing every appliance and worked out a load calculation. Two other contractors just gave me a per-point rate. The finished job came with a circuit schedule and test readings, and every MCB in the board is labelled. I finally know which breaker does what.
My RCCB had been tripping every night for two weeks and the previous electrician told me to replace the whole board. Ambey's technician isolated the circuits one at a time and found moisture in a terrace light point in about forty minutes. Fixed the fitting, sealed the entry, ₹1,400 total. Honest work.
Twenty-two year old flat with no RCCB and nobody had ever mentioned it. They explained the difference between MCB and RCCB in plain language, showed me the trip time on the tester after fitting, and gave me a certificate. Small job, done like it mattered.
