Description
Store more of your daytime solar generation for use in the evening with this MICROMALL 29kWh solar battery pack. Two BTL-48V300M LiFePO4 modules provide 560Ah of combined rated capacity at 51.2V, with 27.2kWh of specified usable energy.
The raised-base design lifts the battery stack clear of the floor, leaving space beneath the base for cleaning and visual checks. Four support legs provide the elevated configuration while keeping the same compact 790 × 275 mm footprint as the Low Profile version. Overall height is 980 mm.
More solar storage in a compact stack
-
Two battery modules, one footprint. Stack the batteries vertically to increase storage capacity without placing them side by side.
-
LiFePO4 chemistry with active balancing. Each BTL-48V300M module includes active cell equalisation to help maintain balance during operation.
-
Communication for system integration. CAN2.0 and RS485 connections support communication with compatible inverters. The modules also include Bluetooth and Wi-Fi.
