Always Ready. Power That Lasts.
LiTime Lares Series. Ready in Minutes.
No electrician or electrical panel changes needed.
Slim Enough to Fit Right In
At just 85mm thick, Lares K1 brings backup power into your kitchen while taking up minimal space.
Set It Up Your Way
The Split Design lets you place the battery and Solar Inverter Charger together or apart, on the wall or floor. A space-saving 90° plug, 0.25m and 1.5m connection cables, and all required mounting accessories are included.
Control Your Power. Wherever You Are.
Storm approaching while you’re away? Use the LiTime App to start charging remotely and get ready for a possible outage. Monitor and manage power on the touchscreen or in the App, with TOU scheduling for off-peak charging and peak-hour battery use.
Split Design. Built to Last.
Separating the Solar Inverter Charger from the battery reduces heat transfer, helping preserve battery health and runtime over time. Efficient cooling helps limit fan run time, with quiet operation at around 40 dB.
LiTime Battery Expertise. Now in Your Kitchen.
Lares K1 brings LiTime’s LiFePO₄ battery expertise to kitchen backup, backed by a 5-year battery warranty and 24/7 expert support.
AC or Solar. Recharge Your Way.
Recharge from a wall outlet at up to 1,500W or from solar panels at up to 800W. Solar charging cable included.

Lares K1 provides backup power for refrigerators, freezers and kitchen essentials such as microwaves, coffee makers and toaster ovens. It delivers 2,000W of continuous output and 4,000W of peak output for startup surges. Check your appliances'running and startup power requirements before connecting them.
For a combined setup, dimensions vary by mounting option:
· With floor stand: System body dimensions are 20.47 × 30.71 × 3.94 in (520 × 780 × 100 mm). Each floor-stand foot measures 9.84 × 2.76 in (250 × 70 mm), so allow additional floor space for the feet.
· With wall-mount brackets: Combined system dimensions are 20.47 × 30.71 × 3.74 in (520 × 780 × 95 mm).
The battery and Solar Inverter Charger can also be placed separately to fit your space, with no brackets needed.
Lares K1 includes the accessories for flexible placement:
· Floor-stand accessories for a combined upright setup.
· Wall-mount accessories for the battery pack and Solar Inverter Charger.
· 0.25 m and 1.5 m battery connection cables for combined and separated setups, respectively.
· An AC power cord with a 90° plug for easier connections in tight spaces.
· A solar connection cable with MC4 connectors for compatible solar panels.
You can also place the battery horizontally with the Solar Inverter Charger stacked on top, without mounting brackets.
No. Lares K1 is designed for stationary indoor home use. It is not intended for boats, RVs or other environments with continuous vibration or movement.
Currently, Lares K1 is available as a complete system or bundled with additional battery packs. The Lares K1 Battery Pack and Solar Inverter Charger will be available for separate purchase in the future.
One 2,304Wh battery pack provides an estimated 24+ hours of backup for a refrigerator using 2 kWh per day. Expand to four battery packs for approximately 99 hours.
Estimates assume 90% inverter efficiency and the refrigerator as the only connected load. Actual runtime varies with the refrigerator, usage, ambient temperature and other connected appliances.
Yes, provided their combined continuous power draw stays within 2,000W and startup surges stay within the system’s 4,000W peak rating. Depending on your appliances’ power requirements, you can keep your refrigerator running while using one microwave, coffee maker or toaster oven.
Yes. With Lares K1 set up for backup and your appliances connected to its AC outlets, the built-in UPS switches to battery power in 10 milliseconds or less when grid power fails.
Yes. Lares K1 supports up to four compatible K1 Battery Packs, expanding capacity from 2,304Wh to 9,216Wh. Adding battery packs extends runtime; continuous output remains 2,000W.
