Inverter and home UPS prices in Nepal (2026)
The inverter price in Nepal in 2026 depends on capacity and whether you want plain home UPS or solar-ready hybrid. A 600VA home UPS suitable for lights, fans and a router costs Rs 7,500–11,000. A 1kVA unit — the most common Kathmandu household size — runs Rs 10,000–16,000. A 1.5–2kVA inverter that can also carry a TV, fridge compressor cycles or a small microwave sits at Rs 15,000–28,000. Solar hybrid 1kVA models with MPPT charge controllers run Rs 22,000–40,000 before panels.
Home UPS and inverter are used almost interchangeably in Nepal; true home UPS units have built-in changeover and are tuned for switch-on under load, while inverters plus an external changeover switch are common in solar-ready setups. SDR Smart Design and Repair supplies and installs the mainstream brands — Microtek, Luminous, Su-Kam, Felicity and APC — with a written NPR quote and warranty card on 9801508528.
- 600VA home UPS: Rs 7,500–11,000
- 1kVA home UPS: Rs 10,000–16,000
- 1.5kVA home UPS: Rs 14,000–22,000
- 2kVA home UPS: Rs 18,000–28,000
- Solar hybrid 1kVA (MPPT): Rs 22,000–40,000
- Pure sine wave premium models: add 15–30%
Battery prices: the half of the budget people forget
An inverter is useless without a battery, and the battery often costs nearly as much. Tubular batteries — the default for daily load shedding — price out at Rs 9,000–16,000 for 100Ah and Rs 13,000–22,000 for 150Ah, depending on brand and plate thickness. SMF/maintenance-free batteries cost more upfront (Rs 12,000–25,000) but need no top-ups. A quality tubular battery lasts 3–5 years with monthly distilled-water checks; a cheap flat-plate battery may be dead in 18 months.
Pair capacity sensibly: a 1kVA inverter with a 150Ah tubular battery typically runs 2 fans, 4–6 LED bulbs, a router and a TV for 5–8 hours. Push a fridge onto the same bank and runtime collapses to 1–3 hours with deep discharge that shortens battery life. SDR sizes the inverter, battery and cable together so the numbers on the box match the load you actually plan to run.
- Tubular 100Ah battery: Rs 9,000–16,000
- Tubular 150Ah battery: Rs 13,000–22,000
- SMF / maintenance-free 100Ah: Rs 12,000–20,000
- Battery life: 3–5 years tubular with monthly checks
- Distilled water top-up: every 2–4 weeks in dry season
- Do not discharge below 50% — it halves battery life
Installation and wiring cost (NPR)
Installation is where safety decisions live. Proper setup includes a wall-mounted inverter location with ventilation, battery in an open or ventilated box away from living-space foot traffic, 2.5–4 sq mm cable on the inverter output, a DP changeover or the UPS built-in transfer, earthing of the battery negative to a common point, and labelling which MCB feeds the backup circuit. In Kathmandu this complete setup costs Rs 1,500–3,500 in labour and hardware on top of the unit price.
Skipped steps are common and dangerous: thin cable that heats, battery acid boxes in a child’s bedroom, no ventilation on an inverter stuffed in a cupboard, and output wired straight into the main board without changeover protection. SDR quotes installation separately with the cable size named on the slip, tests load transfer live, and shows you the switchover before we leave. Emergency or same-day installs call 9801508528.
- Standard inverter + battery install: Rs 1,500–3,500
- Includes wall mount, cable, DP switch, testing, labels
- Output cable: 2.5–4 sq mm copper for 1–2kVA
- Ventilated battery location — never a sealed cupboard
- Earthing/negative bonding and changeover check included
What can a home UPS run? Load planning checklist
Before you buy, list what must survive a cut and check each item’s wattage. Lights and fans are cheap load; heating elements and compressor starts are not. A 1kVA/1000W inverter comfortably carries LED lighting, two fans, a router, a set-top box and a 32" TV. Add a 150Ah battery and you get a full evening of that load. A fridge needs at least 1.5–2kVA with matched battery, and an immersion heater or air conditioner is simply outside home UPS territory in Nepal — plan generator or NEA backup for those.
Add the wattages, keep 20% headroom, and size the inverter above the total. Running an inverter at 90–100% load constantly shortens its life and triggers shutdowns. SDR does this load calculation free over the phone — call 9801508528 with your appliance list — or read the full method at /blog/electrical-load-calculation-nepal.
- LED bulb 9W × 8 = 72W
- Ceiling fan 50–75W × 3 = 225W
- Router + TV: 80–150W
- Fridge (compressor cycles): 150–300W surge-heavy — needs 1.5kVA+
- Immersion heater / AC / microwave: not for home UPS
- Keep 20% inverter headroom above total running watts
Buying checklist: inverter purchase in Kathmandu
Buy on specs, not the loudest shop sign. Confirm pure sine wave output for sensitive electronics, the VA rating against your wattage total, battery compatibility (tubular profile and Ah), warranty length (2 years on unit is standard, batteries 12–18 months), and whether the price includes installation or it is an add-on. Test the changeover in the shop or on delivery — the unit should pick up the load within 10–20 ms without you flipping anything.
SDR Smart Design and Repair supplies genuine units with full warranty paperwork and installs them the same day across Kathmandu Valley. Get an itemised NPR quote covering inverter, battery, cable, mount and labour before paying — then keep the battery water schedule or your warranty can void. Ready to price a complete backup system?
