5 kVA Lithium Inverter (Wall-Mounted): 1 Battery, Runs Your AC

5 kVA Lithium Inverter (Wall-Mounted): 1 Battery, Runs Your AC

The Su-vastika 5 kVA lithium inverter is a wall-mounted, space-saving power-backup solution that replaces the bulky four lead-acid batteries a normal 5 kVA system needs with a single lithium battery bank — faster charging, longer life and almost no maintenance.

A traditional 5 kVA inverter runs on four tubular lead-acid batteries, which take up floor space and need constant upkeep — water topping, terminal cleaning and balancing across the string. The Su-vastika 5 kVA lithium inverter solves all of that: a charger and inverter in one unit, designed specifically for the lithium charging profile, powering the same 5 kVA load from a single, compact, wall-mounted lithium bank.

Why wall-mounted lithium wins

  • Space-saving: the wall-mounted design frees up valuable floor space — ideal for homes, shops and small offices.
  • Lightweight: a lithium bank is far lighter than four tubular batteries, so installation is easy.
  • Long life: 7–10 years vs 2–3 years for tubular, whose backup also drops sharply after a couple of years.
  • Fast charging: charges far quicker than lead-acid, which often needs 12–14 hours.
  • High efficiency: 90%+ usable energy, which also helps your electricity bill.
  • Smart monitoring & BMS: a Battery Management System tracks temperature, voltage and current, protecting against overcharge and overheating, with app monitoring of battery health and charge cycles.
  • MCB protection & scalability: built-in MCB protection, and you can add capacity as your needs grow.

Powerful enough to run your air conditioner

One of the biggest advantages of the 5 kVA lithium inverter is that it is powerful enough to run an air conditioner on backup — something most home inverters simply cannot do. Its pure sine wave output and high surge capacity handle the heavy startup current of a 1–1.5 ton AC, along with your fans, lights, TV and refrigerator, so your home stays cool and comfortable even during long power cuts.

Control it from your phone — Bluetooth & Wi-Fi app

Every Su-vastika lithium inverter comes with a Bluetooth and Wi-Fi mobile app (iOS and Android). From your phone you can monitor and control the inverter, see live battery status, charge level, load and overload warnings, and track battery health and charge cycles — from anywhere, even when you are away from home. See how this works in our guide to the best lithium inverter in India.

What about the price?

The price of a 5 kVA lithium inverter is now close to a 5 kVA system with lead-acid batteries — and since lithium lasts roughly twice as long, it works out cheaper over its life.

Frequently asked questions

How many batteries does a 5 kVA lithium inverter need?
Just one lithium battery bank — compared with four tubular lead-acid batteries for the same 5 kVA load.
Can it run an air conditioner?
Yes — a 5 kVA lithium inverter with pure sine wave output and high surge capacity can run a 1–1.5 ton AC along with normal home loads.
How long does a 5 kVA lithium inverter last?
About 7–10 years, versus 2–3 years for tubular lead-acid — so it’s cheaper over its life despite a similar upfront price.
Is a 5 kVA lithium inverter expensive?
Its price is now close to a 5 kVA lead-acid system, and with roughly double the life and no maintenance, the total cost is lower.
