AIMS Power 5000 Watt 12Volt DC Power Inverter to 240Vac 60Hz

Behaves exactly as described. I'm an EE, so I took it apart to see how it was built. I'm impressed with the construction and design techniques. It's clearly done by people who know what they're about, and do it a lot.

I have a well with a 3/4hp pump (soft start), 2x12.6v 100ah lifepo4 batteries in parallel, 6 series-parallel 100w panels, and a Victron 100/30 MPPT charger. I’d like to confirm what a reviewer “danno” was experiencing with roughly 700wh per day idle wattage and I’m measuring 2.24A idle current (roughly the same 700wh per day as danno, Thanks danno!). With snow covered panels my batteries will be depleted in 3 to 4 days even with no pump use. Drawing 2.24 amps 24/7 is not acceptable when my well usage is a tiny fraction of this. My 3/4hp well pump draws 7.2A for 45 seconds to fill and pressurize the holding tank. Leaving the kitchen tap running, the water will continue to flow for another 6 minutes before the pump turns back on. With such a small duty cycle, the average pump power drawn over a day is miniscule.SOLUTION, with the added modifications I will have to give the inverter 5 stars, it fits my needs perfectly!To eliminate the idle current draw, I now use an additional, water pressure switch, identical to the other standard pressure switch located at the holding tank water manifold that controls the pump. I set the turn-on pressure of this additional pressure switch slightly above the pump normal turn-on pressure. I use this switch to turn on the inverter just before the pump turns on as the water pressure is decreasing. The turn-off pressure is set just below the pump’s normal turn-off pressure. This shuts the power off to the inverter and hence the pump. This means that the new pressure switch is in full control of the pump and the inverter is fully off (no current draw) during idle times.Wire the pressure switch contacts in parallel with the inverter on/off switch, no additional hardware is needed. With the switches in parallel if you slide the switch "on" at the inverter, it will run continuously as normal, slide the switch "off" and the inverter is under water pressure control.Because this second pressure switch circuitry is completely independent from the normal pressure switch, it allows me to unplug the pump from the solar power and plug it into the house current and it works normally just as if no modifications were made.

I have a well with a 1/2hp pump (soft start) and wanted to go full solar. So I put together a 12v solar system (400w, 40amp charge controller, 2x12v 100ah lifepo4 batteries in parallel) to power this baby. Gave it a load test for one hour, pumping somewhere around 300 gallons of water (about 1/3 my monthly usage) and it never skipped a beat. I am very happy with the unit.A couple of notes:- the unit consumes quite a bit of standby power, which is why I took out one star. With no load, the fans come on intermittently. I measured total power use per day at 700wh (about 30w average power use). This is no small chunk of energy if you're running solar, especially with only 400w of panels. So bear that in mind. The system works in my case because I have ample storage power, enough to run the system for a few days with no sunlight.- Speaking of power, usually 1/2hp pumps need somewhere around 1700-2000w to run. So, you will need a battery or batteries that can supply that kind of power. Nominal discharge (for long life) of lithium based batteries is usually 0.5-0.8c (fraction of capacity). In my case, the total capacity for the two batteries is 2.4kwh, and my pump uses around 1700w continuous. So I consider this a minimul setup for a 1/2hp pump. Might want to have three batteries to be on the safe side.I use #2 wires from the battery bank to the inverter. They do get warm under load, around 80-85F. Recommended is to keep them under 90F. So I would also consider #2 wire as minimum to get the job done.Long term update. Two years later, the unit still works. But. Intermittently, it shuts off, not sure why. I now have 4 batteries and monitoring at the time of shutoff they still have plenty of charge (over 80%). The most annoying thing is that I have to manually turn off the back on the unit to get it going again. This involves an inconvenient trip to the pump house, sometimes in the middle of the night in bad weather. I'm now looking to replace it.

AIMS UNIT ARE GREAT. HAVE USED OVER 40 of the 120/240 units not one problem ! (but this is a single phase unit only) using for of grid lighting only....

Bought as emergency backup for well pump, 3/4 hp. Set up to operate off of 6 golf cart LA flooded batteries. Initially concerned about using modified sign wave device but after 5 yrs of occasional use no issues. Would have given it 5 stars except the units cut off low voltage protection for batteries is factory set about 10.5 volts and can't be changed...way to low. robertsames12@gmail.com

Ok

After a year he stopped working. And I do not use it much. But it really sucks

Can't start a 2hp motor at 240v, plan to use stronger 12v deep cycle battery or even 2 batteries, will post results in a few weeks.
