The AIMS Power 230VDC Dual Lithium Battery Cabinet Set pairs a master and a slave LiFePO4 battery cabinet. Each pre-wired cabinet holds six 38.4V lithium packs wired in series for 230.4V and 96Ah, or 22.1 kWh (22,114 watt hours). Together the two cabinets form a 230VDC, 192Ah battery bank that AIMS rates at 44,228 watt hours.
It's made for home and backup power systems built around an AIMS Power hybrid inverter that need stored power for critical loads, load sharing at night or hours when grid power is at peak rates. The master cabinet's BMS is pre-programmed to work with the AIMS hybrid inverter, and the bank connects to it with three wires: positive, negative and CAN.
The lithium packs arrive installed and wired in series inside each cabinet. On the back of the cabinet, the P+ and P- terminals and the COM port connect to the hybrid inverter's BAT+, BAT- and COM (CAN) ports. You don't build a battery rack or wire modules on site.
The master cabinet includes the battery management system (BMS), with cell balancing, and its front panel has battery and COM ports for the master and up to two slave cabinets. Separate 12V batteries wired in series power the BMS. A DIP switch sets the address: with two cabinets, switch number two goes up and the rest stay down.
AIMS rates each cabinet for more than 3,500 cycles and more than 97% efficiency, with LiFePO4 cells in every pack.
Each cabinet handles a maximum charge and discharge current of 50 amps. Discharge cuts off at 180V and the maximum charge voltage is 262.8V. AIMS says the cabinets are more efficient during high watt usage.
The cabinets are rated IP54 and use natural cooling. Each door locks with a key, and eye bolts on top let you lift the cabinet into place.
One AIMS hybrid inverter supports up to three cabinets: one master and two slaves. A slave cabinet must be used with a master, because the master holds the BMS.
Backup for critical loads. Keep critical loads running from stored power during an outage, within your inverter's limits.
Time-of-use savings. With an AIMS hybrid inverter, set the bank to charge when grid rates are low and power your loads during peak hours to help offset your power bill.
Solar storage. Charge the bank from solar first and from the grid only if needed, then use that energy at night.
Night load sharing. Let the battery bank share your loads during night hours.
AIMS says its LiFePO4 design allows deeper depletion of the battery than lead types, in a much more manageable weight and size than a similar lead bank. Each cabinet is rated for more than 3,500 cycles, and the BMS handles cell balancing for you.
Loose rack modules need to be mounted, wired in series and connected to a BMS on site. These cabinets come with the packs installed and wired, so setup comes down to placing the cabinets, linking the slave to the master and running three wires to the inverter.
Each cabinet measures 68.75 inches tall including the eye hooks, 33.75 inches deep and 24.75 inches wide, and AIMS's instructions list 882 lbs per cabinet. Plan floor space for both cabinets and a way to move and lift them. Eye bolts for lifting are included. Operating temperature is -4°F to 140°F and charging temperature is 0°F to 140°F.
The cabinets are designed for AIMS Power hybrid inverters. AIMS recommends an inline fuse between the battery and inverter, installed closest to the battery cabinet on the positive cable. Turn off all power sources before making connections and check polarity, since reversed polarity voids the warranty. AIMS's instructions say the cables and fuse kit that connect the cabinet to the inverter are purchased separately.
AIMS designed these cabinets for AIMS Power hybrid inverters. The BMS comes pre-programmed to work with the AIMS hybrid inverter and talks to it over the CAN connection.
Yes. The master cabinet works with a maximum of two slave cabinets, so one inverter can run up to three cabinets. With three cabinets, DIP switch number three goes up and the rest stay down.
Separate 12V batteries connected in series power the cabinet's BMS. AIMS lists them with the cabinet's included components.
AIMS includes a five-year limited warranty. Reversed polarity at the inverter connection voids it, so double-check your wiring.
Each cabinet holds six 38.4V lithium packs prewired in series, and separate 12V batteries in series power the BMS.
The AIMS Power 230VDC Dual Lithium Battery Cabinet Set gives an AIMS hybrid inverter a 192Ah, 44,228 watt hour LiFePO4 bank in two pre-wired cabinets with one master BMS. If you'd like help planning the installation or matching the set to your inverter, the Outbound Power team is happy to help.
