5-Year Design Life
Engineered for real-world backup power
One compact wall-mounted unit combines the battery, inverter, MPPT solar charger and UPS switchover into a single device — no separate cabinets, no complicated wiring.
Pure Sine Wave Output
Clean 185–230VAC output at 50Hz powers sensitive electronics — TVs, routers, laptops, refrigerators and well pumps without distortion.
Solar PV Input
Connect a single 150–550W solar panel (MC4) and recharge the battery during the day. MPPT range up to 60Vdc on the 1000W model.
Dual Working Modes
Switch between UPS mode (170–280VAC) and Appliance mode (90–280VAC) with a 3-second press — tune sensitivity to your grid quality.
Compact Wall-Mount Design
Slim indoor enclosure installs in minutes with two M5 screws. IP21 rated, just 15cm deep — fits utility rooms, garages and small offices.
USB & Type-C Charging
Two 5V/1A ports keep phones and small devices topped up directly from the unit — no adapter required during an outage.
Three sources, one reliable output
Solar and the grid charge the built-in battery automatically. When the grid fails, the RES unit switches to battery power in UPS time — no dark screens, no frozen food, no interrupted work.
01 · CHARGE
Solar & Grid Input
Energy flows in from a 150–550W solar panel or from the wall outlet. The internal MPPT charger maximises solar yield, while grid tops up the battery on cloudy days.
02 · STORE
LiFePO4 Battery
Energy is stored safely inside the wall-mounted cabinet. BMS monitors each cell, temperature and current to protect against overcharge, over-discharge and overheating.
03 · POWER
Pure Sine Wave Output
When you need it, the inverter delivers clean 230VAC to your appliances. AC outlets, USB and Type-C ports are ready — UPS mode handles the switchover automatically.

Where the RES earns its place
Home Backup During Outages
Keep the router, modem, lights and a small refrigerator running through unexpected blackouts. UPS mode switches over instantly — no reboot, no lost work.
Off-Grid Cabins & Summer Houses
Pair with a single solar panel for remote rooms where grid power is unavailable. Store daylight and use it in the evening, no fuel, no generator noise.
Small Business & Home Office
Protect your router, NAS, monitor and laptop during voltage dips. Wide 90–280VAC Appliance mode tolerates unstable grid in rural or developing markets.
Emergency & Disaster Readiness
Pre-charge before storm season. The wall-mounted unit is always on standby — ready to power communication devices and essential appliances when you need them most.
Frequently asked questions
Can I connect more than one solar panel?
The RES unit is designed for a single 150–550W solar panel. Do not wire multiple panels in series or parallel — exceeding the MPPT range will trigger a PV over-voltage fault.
What is the difference between UPS mode and Appliance mode?
In UPS mode, the unit treats mains outside 170–280VAC as a failure and switches to battery — best for sensitive electronics. In Appliance mode (the default), the wider 90–280VAC range means it will only switch on true outages, not minor voltage fluctuations. Toggle by holding SET for 3 seconds.
Is installation difficult?
No. The unit can stand vertically on a shelf, or be wall-mounted with two M5×30mm screws into wall anchors. Mark 125.8mm on centre, drill 6mm holes 40mm deep, fix the bracket, hang the unit. Connect solar and AC input last.
Can I use it outdoors?
No. The RES is IP21 rated and designed for indoor use only. Install it in a ventilated, dry room away from flammable materials and direct sunlight.
What happens if the battery runs low?
The built-in BMS stops discharge when the battery reaches low-voltage protection. When solar or grid power returns, it automatically resumes charging — no manual intervention required.
