LiTime launches the Lares K1 Backup Power System on October 20, 2026. Designed for refrigerators and essential kitchen appliances, this plug-in battery backup combines automatic switching, expandable storage, and flexible installation for household outage preparation.
K1 pairs a solar inverter charger with a 2,304Wh LiFePO₄ battery. Its separate components can be installed together or apart to suit different household spaces.
Automatic Backup Power for Refrigerators and Kitchen Essentials
Everyday outages, overnight interruptions, and power failures while residents are away can disrupt refrigeration before anyone can respond. Thunderstorms, hurricanes, and winter storms may also leave households without electricity for longer periods.
Refrigerator Backup with Automatic UPS Switching
Lares K1 provides an estimated 24+ hours of refrigerator backup from one 2,304Wh battery, based on a refrigerator consuming 2kWh per day. Its uninterruptible power supply (UPS) function switches to battery power in 10 milliseconds or less when grid power fails, without requiring a manual changeover.
For households storing fresh groceries, frozen meals, or breast milk, this automatic response helps maintain refrigerator operation when an outage begins.
Output Capacity for Additional Kitchen Appliances
K1 delivers 2,000W of continuous AC output and 4,000W of peak power, supporting refrigerator compressor startup and compatible kitchen appliances. Depending on the combined load, households can also use an appliance such as a microwave or coffee maker to support basic meal preparation during an outage.
Two AC outlets, one on each side of the inverter charger, allow different appliances to remain connected and provide flexibility in appliance placement. This approach allows households to prioritize refrigeration while retaining options for other necessary kitchen tasks.
Separate Components for Flexible Installation and Long-Term Use
Slim Design and Multiple Installation Options
K1’s 85mm slim system profile is designed to limit the space required for household backup power. Wall-mounted and floor-standing installation options, together with combined or separated component placement, allow the layout to be adapted to suitable installation conditions.
Required mounting accessories are included. The installation choices give households flexibility when considering available floor or wall space, access to controls, and appliance connections.
The separate inverter charger and battery also reduce heat transfer from the power-conversion components to the battery, helping preserve long-term battery health and runtime. The battery is backed by a five-year warranty.
System Monitoring and Indoor Operation
A built-in touchscreen displays real-time energy status and allows users to adjust system settings directly on the inverter charger. Wi-Fi and Bluetooth 5.0 connectivity also support monitoring and control through the LiTime App. Users can access information through the onboard screen or the App according to their needs.
K1 is designed for indoor use with operating noise around 40dB. High-efficiency components generate less heat, reducing fan runtime and supporting quieter operation in the home.
Expandable Storage and Flexible Recharging
For households preparing for longer interruptions, K1 supports up to four batteries connected in parallel, increasing total storage from 2,304Wh to 9,216Wh. 
Adding batteries increases stored energy and potential runtime. The system’s AC output remains 2,000W continuous and 4,000W peak across these configurations.
K1 supports AC charging at up to 1,500W and solar input at up to 800W, with a maximum total charging power of 1,500W. These options provide flexibility in replenishing stored energy; solar charging requires compatible equipment and suitable installation and sunlight conditions.
