The AIMS Power 12000 Watt Off Grid Backup Kit (KITC-12K48240) combines an industrial grade 12,000 watt low frequency pure sine inverter charger with two high-capacity 48V lithium batteries, a 6 ft battery to inverter cable set, jumper cables to connect the batteries and a fuse kit. It's a complete backup system that charges from the grid and switches to battery power automatically during an outage.
AIMS built this kit for larger homes, businesses, workshops and commercial applications with bigger electrical loads. It can power multiple high-demand appliances, including refrigerators and freezers, well pumps, HVAC equipment, lighting, electronics and tools, while keeping the installation simple.
The inverter charger is rated for 12,000 watts continuous with a 36,000 watt surge, and it delivers true 120/240V split phase output for demanding residential and commercial loads. Its low frequency design and 300% surge rating help with equipment that draws extra power at start-up. AIMS states that the inverter charger is listed to UL standards.
An integrated automatic transfer switch moves connected loads from utility power to battery power when the grid goes down, with no manual intervention. When utility power returns, the built-in charger starts recharging both batteries.
Two high-capacity 48V lithium batteries provide extended runtime and greater backup capacity. AIMS states that they deliver full usable capacity, need virtually no maintenance, have no memory effect and offer up to eight times the charge and discharge cycle life of lead-acid, gel or AGM batteries.
The inverter charger includes its own battery charger, so you don't need a separate one. It keeps both batteries topped up whenever utility power is available, so the system is ready for the next outage.
Auto generator start supports extended backup with a compatible generator. A battery temperature sensor, adjustable AC priority settings and configurable operating modes let you tune the system, and an optional LCD remote connects to the remote port.
The rear panel groups the DC terminals, DIP switches, LCD remote port, battery temperature sensor port, auto generator start terminal, circuit breakers and the AC hardwire terminal block. Intelligent cooling fans manage heat during heavy use.
Larger home backup. Keep refrigerators, freezers, lighting and electronics running through an outage in a larger home.
Homes with HVAC and well pumps. AIMS lists HVAC equipment and well pumps among the high-demand loads this system can power.
Businesses and commercial sites. Back up essential equipment so work continues when utility power is unavailable.
Workshops. Run lighting, electronics and tools in a shop during an outage.
Large RVs. AIMS notes the system can serve large RV backup needs with split phase power.
A fuel generator needs fuel on hand, routine maintenance and usually someone to start it. This kit takes over automatically, runs without fuel and recharges from the grid. With auto generator start, you can still pair it with a generator when an outage runs long.
A lead-acid bank sized for this much backup takes many batteries, more wiring and regular upkeep. This kit uses two 48V lithium batteries joined with the included jumper cables, and AIMS rates them for up to eight times the cycle life of lead-acid, gel or AGM batteries.
Building backup power from a standalone inverter means adding a separate charger and transfer switch. This inverter charger combines all three, which simplifies mounting and wiring.
List the appliances you want to run at the same time and add up their wattage. Keep the total under the 12,000 watt continuous rating, and use the 36,000 watt surge rating as headroom for motor start-ups. Runtime depends on your loads and how long you run them, so the Outbound Power team can help you estimate it.
The inverter charger measures 23.3 x 16.3 x 8.0 in and weighs 154 lbs, so it needs a solid mounting surface. Leave room for the two batteries and their jumper cables near the inverter charger. Because the AC side hardwires into your building wiring, plan the install with a qualified electrician.
AIMS includes jumper cables to connect the batteries, plus a 6 ft battery to inverter cable set and a fuse kit.
Yes. The built-in charger recharges both lithium batteries automatically whenever utility power is available.
AIMS rates the inverter charger for 12,000 watts continuous and 36,000 watts of surge, which is 300% of its continuous rating.
Yes. The inverter charger supports auto generator start for extended backup. The Outbound Power team can help you plan the generator connection.
No. The LCD remote is optional and plugs into the remote port on the inverter charger.
The AIMS Power 12000 Watt Off Grid Backup Kit brings a 12,000 watt split phase pure sine inverter charger, two 48V lithium batteries, cables and a fuse kit together into one backup system for larger energy demands. If you'd like help sizing your loads, planning the installation or pairing a generator, the Outbound Power team is happy to help.
