Description

APsystems Lake-6 is the AC-coupled battery storage for anyone who wants to easily expand an existing photovoltaic system with a battery storage unit. With a usable capacity of 6.02 kWh and a charge/discharge power of 2,500 W, you store your solar power and use it exactly when your household needs it. Thanks to its plug-and-play design, installation is quick and straightforward.

Main Benefits for Your Home

Easy retrofitting: As an AC-coupled battery storage, the Lake-6 is compatible with existing PV systems and can be integrated independently of the existing inverter.
Long service life: The LiFePO4 battery technology achieves over 8,000 charge cycles, ensuring reliable operation for many years.
Quiet operation & weather protection: With ≤30 dB, the battery storage operates whisper-quiet, and the IP65 protection rating also allows for flexible placement.
Full monitoring: Via Wi-Fi, Bluetooth, LAN, and RS-485, you can keep track of your energy flow at all times.

Intelligent Use of Your Solar Power

A modern battery storage ensures that valuable solar energy doesn't flow unused into the grid, but is instead available when your family needs it. The APsystems Lake-6 battery storage works with an intelligent battery management system (BMS) that precisely controls the cells and maximizes service life. Thanks to AC coupling, the battery storage integrates seamlessly into your existing photovoltaic system, without any intervention in the existing inverter. With features such as zero feed-in, time-controlled scheduling, and backup power, you increase your self-consumption and gain a significant degree of independence from the public grid. This noticeably lowers your electricity costs and lets you use your self-generated power around the clock.
