AIMS Power Bull Expedition Solar Kit | 800W Solar, 3000W Inverter Charger, 5.1kWh AGM Battery

The AIMS Power Bull Expedition Solar Kit Pairs 800W of Solar With a 3000W Inverter Charger and a 50A Transfer Switch for Large RVs and Mobile Businesses

The AIMS Power Bull Expedition Solar Kit (ECBULL) is a complete solar power system for large RVs, vans, buses and mobile businesses. It combines four 200 watt N-type monocrystalline solar panels, a 60 amp MPPT charge controller, two 12V 200Ah AGM deep cycle batteries rated at 400Ah and 5.1 kWh in total, and a 3000 watt low frequency pure sine inverter charger with a 50A automatic transfer switch. Brackets, fuses, PV wire, an entry gland and a quick DC disconnect complete the kit.

AIMS calls the Bull one of its largest mobile complete systems. It's built for people who run high-demand appliances and need steady power whether they're off-grid, on the road or plugged in to shore power.

AIMS Power Bull Expedition Solar Kit Features

Automatic Switching Between Shore Power and Battery

The inverter charger has a built-in 50 amp transfer switch. AIMS describes it as a 120/240V 30A and 50A transfer that moves your loads from grid or shore power to inverter power automatically, so connected devices keep running when you unplug. AC wiring connects at a hardwire terminal block next to a GFCI outlet.

3000 Watts of Pure Sine Power for Heavy Loads

The low frequency inverter charger delivers 3000 watts continuous at 120 VAC with a 9000 watt surge rating, listed by AIMS as 25 amps continuous and 75 amps surge. AIMS names compressors, pumps, motors and large variable speed appliances among the loads it can power.

A Built-In 100 Amp Battery Charger

When you plug in to shore power or the grid, the inverter charger also charges your batteries. AIMS lists a 100 amp AC charger, so one unit powers your loads and manages charging.

5.1 kWh of AGM Battery Storage

Two AIMS AGM12V200A 12V 200Ah deep cycle batteries give you 400Ah in total, which AIMS rates at 5.1 kWh. They're valve regulated rechargeable batteries and come with battery cables. AIMS lists battery expansion as an option if your needs grow.

800 Watts of N-Type Solar With a 60 Amp MPPT Controller

Four 200 watt N-type monocrystalline panels in aluminum frames recharge the battery bank during the day, which cuts how often you need a generator. Each panel measures 49.2 x 30.12 x 1.18 inches with 31.5 inch MC4 type leads. A 60 amp MPPT charge controller with an LCD screen manages charging.

Fuses, Wiring and a Quick DC Disconnect in the Box

AIMS includes a 300A battery to inverter fuse, an 80A charge controller to battery fuse and an inline solar fuse. You also get 20 ft of PV wire, an MC4 type entry gland with 10 ft leads, 8 ft inverter cables and a quick DC disconnect for the PV array.

Real-World Applications

Large RVs and buses. AIMS lists whole coach off-grid power and residential fridge operation among the common uses.

Mobile service businesses. AIMS names mobile dog grooming vans, mobile detailing and pressure washing rigs, and mobile mechanics and service rigs as good matches.

Food trucks and espresso carts. AIMS lists microwaves, convection ovens, air fryers, electric kettles, coffee makers and induction cooktops among the appliances this kit can run.

Contractor and field service trucks. Run tools, electronics and LED lights on construction trucks or utility and telecom field service vehicles.

Off-grid remote work. Keep electronics, LED lights and a CPAP machine running away from shore power.

Practical Comparison

Bull Kit Versus an Inverter Without a Transfer Switch

A plain inverter runs only from batteries, so using shore power means moving plugs or adding a separate switch. The Bull's inverter charger powers your loads from shore power, recharges the batteries and switches back to battery power on its own.

Low Frequency Inverter Charger Versus a Smaller Surge Rating

Motors, compressors and pumps draw extra power for a moment when they start. The Bull's inverter charger lists a 9000 watt surge, three times its 3000 watt continuous rating, which is why AIMS names high surge loads among its uses. When you compare systems, check the surge rating against your largest motor load.

Complete Kit Versus Buying Parts Separately

Building a system from separate parts means matching every component yourself. AIMS pre-matches the parts in the Bull to work together, which removes the guesswork and shortens the install.

Buyer Guidance

Plan Your Roof Space and Your Loads

AIMS says you need about 40 square feet for the four panels, so measure your roof before you order. Add up the wattage of everything you plan to run at once and keep it under the 3000 watt continuous rating. How long the batteries last depends on what you run and how charged they are.

Expansion and Optional Remotes

AIMS lists battery expansion for this kit but not panel expansion. Optional controls for the inverter charger, not included in the kit, are the BT-AIMS-PRO Bluetooth dongle, the REMLFLCDIGN ignition switch and the REMOTELF LCD and on/off remote.

This May Be A Good Fit If

• You have a large RV, bus or coach with shore power
• You run a mobile business from a van or truck
• You need 3000 watts for kitchen appliances or tools
• You have about 40 square feet of roof space

Common Questions

Does the Kit Work With Shore Power?

Yes. The inverter charger takes 120/240V input and has a 50A automatic transfer switch. While you're plugged in, it powers your loads and charges the batteries. When shore power goes away, it switches to battery power.

What Batteries Are Included?

Two AIMS AGM12V200A 12V 200Ah AGM deep cycle batteries with battery cables, for 400Ah and 5.1 kWh in total. The label lists a 14.4 to 14.7V charge for cycle use and an initial current of less than 60A.

Can I Add More Panels or Batteries Later?

AIMS lists batteries as an expansion option for this kit, but not panels. The Outbound Power team can help you plan a battery addition that matches your bank.

What Warranty Does AIMS Give?

AIMS states a warranty of 2 to 25 years that is product specific, so the term depends on the component.
