The all-in-one portable back-up inverter battery system .
Description:
Reliable Power Backup for Load Shedding
This all-in-one portable inverter system ensures uninterrupted power during outages. Designed for homes and small businesses, it integrates a 3.5kVA pure sine wave inverter with a 24V lithium-compatible battery system, providing stable electricity for essential devices like TVs, WiFi routers, lights, and chargers.
A plug-and-play power system is a simple backup solution that provides electricity during load shedding or power outages—no complex installation required.
How It Works:
- Plug it into a wall socket – The system charges its built-in battery while the power is on.
- Automatic Power Switching – When the electricity goes off, the system instantly switches to battery power.
- Keep Essentials Running – You can plug in WiFi, TV, lights, laptops, and chargers directly into the system.
- Recharge When Power Returns – Once the electricity comes back, the system automatically recharges for the next outage.
- Solar Ready (Optional) – You can add solar panels to charge the system even when there is no grid power.
