The AIMS Power 230V 96Ah LiFePO4 Slave Battery Cabinet (LFP230V96A-S) expands an existing AIMS hybrid inverter battery system. AIMS designed it specifically to connect to the master lithium battery cabinet (LFP230V96A-M), and it increases total available battery capacity through parallel expansion. Each cabinet holds six 38.4V lithium packs prewired in series for 230.4V DC, 96Ah and 22.1kWh (22,114 watt hours).
It's for homes, businesses and backup systems that already have, or are planning, an LFP230V96A-M master cabinet and want more stored energy for critical loads, nighttime use or peak-rate hours. AIMS requires one master cabinet and allows up to two slave cabinets, for up to three cabinets per hybrid inverter.
The slave cabinet adds capacity by connecting to the master cabinet, and AIMS says battery management for the system is integrated through the master cabinet. Adding a slave increases the total stored energy available to your AIMS hybrid inverter for longer runtime.
Each slave cabinet holds six 38.4V lithium packs prewired in series, the same 22.1kWh as the master cabinet. With one master and two slaves, a system can have three cabinets.
The cabinet arrives pre-wired, so installers connect it to the master cabinet using only three wires. On the BMS front panel, B2 and B3 are the slave battery connections and COM2 and COM3 are the slave communication ports, while B1 and COM1 are the master.
When it's paired with the master cabinet and your hybrid inverter, the system can be set to charge from solar or grid power, or to discharge during peak electricity pricing to help reduce energy costs.
AIMS rates the cabinet at greater than 97% efficiency and the packs at more than 3500 cycles. Maximum charge and discharge current is 50A. Cell balancing and natural cooling help keep performance stable under high loads.
The cabinet is rated IP54 and has a locking door with a cabinet key. Four eyehooks come with it, and the 68.75 inch height includes the eye hooks.
Longer backup time. Add 22.1kWh to an existing master cabinet so critical loads run longer during an outage.
More solar stored for night. Store more daytime solar energy for nighttime consumption.
Bigger peak-rate savings. Hold more grid or solar energy to run loads through peak utility rate periods.
Growing systems. Start with a master cabinet and add slave cabinets as power demands grow, for residential backup, off-grid or commercial systems.
The master cabinet (LFP230V96A-M) connects to the AIMS hybrid inverter, and its BMS front panel has the ports for the master and slave batteries. The slave cabinet connects to the master and can't be used on its own. Both hold the same six prewired 38.4V packs for 22.1kWh each.
Separate batteries have to be wired and set up one at a time. The LFP230V96A-S arrives with its packs prewired in series and connects to the master with three wires, so expanding the system stays simple.
A slave cabinet only works with an LFP230V96A-M master cabinet. AIMS allows a maximum of two slave cabinets with one master. When you add cabinets, set the ADDR dip switch for the number of cabinets: dip switch two up for two cabinets or dip switch three up for three, with all other switches down. Dip switch four isn't used.
Each cabinet weighs 882 lbs and measures 68.75 inches high, 33.75 inches deep and 24.75 inches wide, so plan the floor space and how you'll move it into place. Turn off all power sources before making connections, and never reverse the polarity, which AIMS says voids the warranty.
No. AIMS designed it specifically to connect to the LFP230V96A-M master cabinet, and one master is required.
Up to two. AIMS says the master battery cabinet works with two slave batteries at most, for three cabinets per hybrid inverter.
Nominal voltage is 230.4V DC. AIMS lists a maximum charge voltage of 262.8V and a discharge cut-off of 180V.
AIMS rates operation from -4°F to 140°F and charging from 0°F to 140°F.
Please check with the Outbound Power team about the cables for the connection to your master cabinet before you install.
The AIMS Power 230V 96Ah LiFePO4 Slave Battery Cabinet adds 22.1kWh of pre-wired lithium storage to an LFP230V96A-M master cabinet with a simple three-wire connection. If you'd like help planning a two or three cabinet system, the Outbound Power team is happy to help.
