KEMOT PROsinus-1500/24-LFP4 Pure Sine Wave UPS Inverter 1500VA/1050W 24V DC to 230V AC with Battery Charger

Power outages and unstable mains supply can disrupt critical equipment, damage sensitive electronics, or halt operations entirely. The KEMOT PROsinus-1500/24-LFP4 is a robust emergency power solution that converts 24V DC from a battery bank into clean 230V AC power with a pure sine wave output. It delivers 1500VA/1050W continuous power and can handle surges up to 4500W for 5 seconds, making it ideal for demanding loads like motors, pumps, and modern appliances. The built-in battery charger supports AGM, Gel, and LiFePO4 batteries, ensuring your backup system is always ready. With a transfer time of ≤4 ms, connected devices experience virtually no interruption when mains power fails. The LCD display provides real-time status of input voltage, output voltage, load level, and battery condition, while comprehensive protections guard against overload, short circuit, over/under voltage, and overheating. Housed in a sturdy metal enclosure with fan cooling, this inverter is built for reliable long-term operation in homes, offices, workshops, and off-grid installations.
