This is the power inverter in my off the grid setup.

It was the cheapest money can buy for the rated capacity

This full sine wave power inverter was designed with top quality and durability in mind and is built to survive 10+ years in the harshest conditions (and has met and exceeded those expectations).
It is commonplace to use a fuel-powered generator to power tools and appliances off-the-grid, but this is a terribly inefficient and environmentally harmful way to make AC power due to the carbon dioxide emissions.
You can save the planet by switching to a green power inverter and at the same time save your wallet too if you’re buying our cost-effective 12000 watt inverter as it is a three-in-one product: power inverter, battery charger and transfer switch.
The 12000 watt inverter gives out 300% surge power of 36KW for 20 seconds to meet your household or business’s energy needs, meaning, you no longer have to oversize inverter wattage to meet high surges from loads, less initial investment.
Our full sine wave 12KW inverter works with very little power loss, outputs an average THD of 3% , its idle consumption is 180 watts, and its peak DC to AC efficiency is notably 90% .
It will significantly outperform any other competing 12KW inverter models in terms of operating costs over the long-term as it reduces battery discharge cycles and prolongs battery life.
The built-in transfer switch allows it to automatically switch between battery bank and shore power (or generators) with a transfer time of 10 mili seconds.
If you are using a generator instead of utility power as backup, the auto generator starter on the full sine wave inverter will automatically start the generator when battery voltage is low enough.
It gives emergency backup power for your residences and business or reliable electricity to your hunting cabin or off-grid vacation home.
It is built-in 120 amp battery charger uses AC power, from the grid or from a generator, to recharge a battery bank.
This UL 1741 compliant 12KW inverter is capable of outputting 12KW at 40 degrees Celsius and withstanding thermal fluctuations because of its over-temperature protection and thermally-controlled fans.
It’s protected from humidity or airborne dust and dirt thanks to its conformal-coated (or “marine-coated”) boards.
This UL 1741 compliant 12000 watt inverter is split-phase, it requires a 240Vac input (single-phase 240Vac or two hot lines of 120Vac), and will output 120 or 220/230/240Vac at 50 or 60Hz. The output winding is center-tapped and the center tap connected to a grounded neutral.
Every percentage of power efficiency matters in large power systems, a low efficiency inverter saves you pennies at startup but steals pounds away from you in the long run.
Make the right choice when build the next renewable power system for your sustainable living.
