AIMS Power builds 48 volt inverters in modified sine, pure sine, and pure sine inverter charger configurations, most of them split phase with a battery charger and transfer switch built in. A 48 volt bank moves the same power at a quarter the current of a 12 volt system, which is why off-grid homes and large solar installations land here.
A low frequency split phase inverter that runs 120 and 240 volt AC loads off the same 48 volt battery bank, with the charger and transfer switch built in.
A split phase inverter charger sized for whole home backup and light commercial off-grid power, with the charger and transfer switch built in.
The largest 48 volt inverter charger AIMS builds, sized to carry a whole house or a small commercial building on battery power.
Spec 48 volts on any array large enough to justify it, then pair the inverter with a matched solar charge controller and solar panels.
Move large coaches to a 48 volt platform, so the same solar power supports air conditioning and a full 120/240 VAC panel.
Run high draw equipment off a 48 volt bank without the cable size a 12 volt system of the same wattage would demand.
Integrate a 48 volt inverter into golf cart, utility vehicle, and equipment builds at volume pricing. Apply to become a reseller for dealer pricing.
Support onboard HVAC and passenger AC power from a 48 volt system that keeps conductor sizing manageable.
I had a question about bonding neutral to ground on my 3000 Watt inverter and the tech took the time to check with the engineers to find the answer for my specific situation.
I had a question about the 6000 WATT 240V split phase I bought a few years back. Being a novice to the exact workings of this device I sent a detailed description of what I thought the problem was. A tech responded quickly and addressed every concern I had. In short, electrical test equipment specifically meant for a normal home electrical system is not meant to test an inverter. In my case I was using a simple plug in type outlet tester. I explained the situation I thought I had and the engineer walked me through it.
Due to user error, I had an issue with my AIMSÂ inverter/charger. The tech support at AIMS was incredibly responsive and walked me through troubleshooting until I discovered the error on my end. I have emailed other companies for tech support and never received responses, AIMS was responding within minutes and repeatedly over a period of a few days until the problem was solved. Truly exceptional customer support from Sky McDermont, and the entire AIMS tech support team.
48 Volt work is where the whole system has to line up, since the inverter, the battery bank, the charge controller, and the array all have to agree on voltage and current. We build every one of those parts, so a single call gets you answers on all of them instead of four vendors pointing at each other.
A 6000 watt load pulls roughly 125 amps at 48 volts against 500 amps at 12 volts. That drop in current is the whole reason to go to 48, since it means far smaller cable and fuses, and less energy lost on long runs. Below about 3000 watts a 12 volt or 24 volt inverter is usually the better fit.
A split phase inverter puts out 120 and 240 VAC at the same time, which is what a standard residential panel expects. You need one if the build runs a well pump, a dryer, a welder, or central air. If every load is 120 volt only, a single phase unit costs less. Our 48 volt inverter chargers are split phase for multi-voltage loads.
A 48 volt inverter needs four 12 volt batteries in series, or a purpose built 48 volt pack. LiFePO4 batteries handle the discharge rate these inverters pull better than flooded, gel, or AGM lead acid batteries do, and it gives you most of the rated capacity on every cycle.Â
With these units, yes. The built-in charger runs on AC input from the grid or a generator, not PV input, so solar charging needs its own MPPT controller between the array and the bank. If you want solar priority and battery backup in one box, look at our hybrid inverters instead.
To size a 48 volt off-grid system, start from the peak simultaneous load for the inverter rating, then size the battery bank for your daily energy use and days of autonomy. Our solar calculator runs the numbers from a load list, and our guide to designing a commercial off-grid solar power system walks through the full sequence.Â
