Pure Sine Wave Lithium UPS 5500 — Power That Never Blinks
Power That Never Blinks. Backup That Actually Thinks.
Meet the Pure Sine Wave Lithium UPS 5500 — a clean-power inverter built around an intelligent 44 V lithium battery system and ready for solar from day one. Grid-quality electricity for your home or office, even when the grid has other plans.
One box, zero compromises
Most backup systems make you choose: clean power or affordability, big capacity or smart charging, inverter or solar. The Pure Sine Wave Lithium UPS 5500 refuses to pick. It runs your sensitive electronics on true grid-quality sine wave power, charges a modern lithium pack with a brain that protects every cell, and slots straight into a solar setup so the sun does the heavy lifting whenever it can.
Whether it's a flickering supply, a multi-hour outage, or you're simply tired of paying for power you could be harvesting for free — this is backup that quietly does the right thing in the background.
What makes it special
Engineering you'll feel, even if you never read a spec sheet.
True Pure Sine Wave Output
A smooth, grid-identical waveform — not the choppy "modified" kind. Your fridge, computers, TVs, medical devices and motors run cooler, quieter and longer, with no buzzing or overheating.
Intelligent Lithium Charging
A multi-stage charge cycle — boost, absorption and float — tuned for a 44 V lithium NMC pack. It tops up fast, then eases off gently to maximise battery life instead of cooking it.
Solar-Smart by Design
Pairs with an MPPT solar charge controller and intelligently prioritises sunshine. Once the battery is comfortably charged, it leans on solar even while mains is available — so you spend less from the grid.
Seamless Changeover
When the grid drops, the switch to battery power is fast and synchronised to the mains waveform — so your devices barely notice, and the lights stay on without a stutter.
All-Round Protection
Built-in guards for over- and under-voltage, overload, short-circuit, over-temperature and battery high/low limits. If something's wrong on the line or the load, it reacts in milliseconds.
Smart Monitoring & Sleep
On-board intelligence tracks battery state-of-charge and system status, drives clear LED feedback, and slips into a low-power sleep mode when the battery runs low — saving energy and protecting the pack.
Built around the battery — the way lithium deserves
Lithium isn't just "a better battery." Treated right, it pays you back with years of dependable cycles. This UPS is engineered to treat it right.

Who it's built for
It's a natural fit for homes that need whole-room or whole-floor backup without the hum and heat of cheaper inverters; for small offices and shops that can't afford for the tills, routers or computers to go dark; and for anyone going solar who wants their backup and their panels to work as one smart system instead of two boxes that ignore each other.
