Inverters are used in any electric system where AC power output is needed. You are already familiar with AC power: it is the power in your house when you plug something into the wall. The inverter's job in a solar energy system is to convert the DC electricity, such as from a battery bank, to AC electricity that can be used with typical household appliances. Solar panels also produce DC electricity. Inverters are used in homes, business, RVs and boats. Off Grid Inverters are common in solar electric. Solar electric (or PV) systems can operate with or without batteries. Since each inverter needs proper disconnects on the AC and DC side, often people choose one of our self contained Solar Battery. By mounting one or two inverters on a Solar Battery, that is wired with the appropriate disconnects, you have yourself a neat and safe inverter system.
Sizing an off grid inverter (that needs batteries) is relatively straight forward. It must be large enough to handle the total amount of watts you will be using at one time. Start by listing all of the appliances, etc that you use and their wattages in our load calculator. This form will display the number of watt hours you use in a day. In order to properly size an inverter, consider which of those loads you will be using simultaneously and add up their wattages only. For example, if you will be using the 1500 watt microwave at the same time you will be running 100 watts of lighting and also running a refrigerator that will draw 500 watts of instantaneous power, you will need an inverter that can handle at least 2100 watts (1500 + 100 + 500). Once you have identified a minimum wattage, you will select an inverter that has the same nominal voltage as your battery bank (12, 24, or 48 VDC).
Theta inverters are principally meant to be used with solar, wind or hydro power systems for a home or business totally disconnected from the electric utility company. They can also be used for providing emergency backup power to homes that currently use the power from an electric company. Inverters with the built-in AC charger option are particularly well suited to providing seamless backup power.
Theta Inveters are designed in compact, lightweight and portable! Inverters plug into a vehicle's lighter socket, and are an easy solution for your small power needs. These unique and convenient inverters can be used for small recharging power needs such as video cameras, laptop computers, and cellular phones. AC outlet is built into the face of the Inverter, and this inverter can be used to run your TV, VCR, lights, computer and satellite receiver.
Connect direcly to 12V battery and turn to mini power station for powering small appliances (220-240V).
Ideal for:
Our new upgraded Theta 2.0 Inverters with USB socket for 5VDC power and external fuse compartment for ease of changing fuse.

General opinion over the last few years was that the modified sine wave inverter was dead, and the pure sine wave inverters would rule the world sales of modified sinewave inverters have continued to out-grow sales of sine-wave, proving that there is plenty of life left in this technology. The principle reason is that most of the equipment such as mobile phones, TV, drill chargers and all that type of equipment which used to have a problem working with modified sine wave tends now work fine on modified sine wave as the effected equipment now tends to use switch mode power supplies in there design which works fine with modified sine wave. This meant that rather than the problems getting worse over the years the problems have diminished, however this is not to say that the odd microwave, drill vacuum cleaner would not work (if there is a thyristor control circuit employed then this can still be a issue ) but there is no question this is becoming more rare as the years go past, plus its still usually a lot cheaper to replace a old microwave to a different model which will work rather than spend heavily on a pure sine wave model to make it work.
Solar Power Mart has invested in a new range of modified sine inverters because they are smaller, lower cost, offer better performance, are more efficient and more reliable than sine-wave. We at Solar Power Mart have always found the modified sinewave inverter more than adequate for general requirements in remote homes, boats and vehicles. There is still the odd appliance, such as washing machines, where modified sinewave inverters simply do not work, but all in all they do a great job – especially considering their cost.
The Theta Modified Sine Wave Inverters are CE and ROSH certified products and come with one year limited OEM warranty.

Theta Pure Sine Wave Inverter converts DC power stored in 12V batteries into clean AC. Thera Pure Sine Wave inverters provide power with very low harmonic distortion, no static or humming noise Perfect for HDTVs, computers and other sensitive electronics High and low voltage protection Overload protection Over-temperature protection
The Theta Pure Sine Wave, heavy duty inverter ensures all electrical products run at their very best. It removes all problems linked with modified sine inverters such as small black lines on some TV screens. It works perfectly with satellite controllers, runs microwaves at 100% power, works thryistor controlled devices. They also eliminate problems caused by low cost, non isolated sine wave inverters, such as interference on TV screens, radio and hi-fi noise and works all CD and DVD players. This unit runs all equipment as per the mains – guaranteed.
The 2000-3000 watt unit is capable of running a standard washing mahcine and all thyristor controlled devices which cannot be run by modified sine. However, if there is a washer dryer then the 3000 would be best. The units all come with a standby circuit which offers a 0.2 amp consumptions with no load and a low on line loss of about 1.2 amps if power saver not engaged.
The Theta Pure Sine Wave Inverter is CE and ROHS certified products and come with limited one-year OME warranty.
