4500 sun force inverter internal fans are always on. When I first set it up it use to come on to cool and then go off.


Likely the thermistor used as a thermal sensor shorted out. Either internally, or to the heat siink.

WHAT IS A POWER INVERTER?


A power inverter is an electronic device that converts electricityfrom one form to another. Power inverters have become more popularrecently as the technology has become more efficient and much moreaffordable.

The most popular use for a power inverter isconverting battery electricity into mains electricity. For exampleconverting your car batteries' 12 volts DC into mains electricity 240Volt AC (Australia) or 110 Volt AC (USA).

WHAT POWER INVERTERS WILL HELP YOU DO
  1. Power inverters enablemains operated electrical equipment to be used even where there is nomains outlets, like in your car, caravan or even on your boat!
  2. Powerinverters bring creature comforts from home when you go camping orcaravaning allowing you to use your TV, fridge or electric shaver infact most of the normal mains powered conveniences from the home.
  3. You can charge your laptop in the car even if it doesn't happen tohave a 12 volt adapter. In fact a power inverter can be a very handygadget just to have in your car for those times you need to use a mainspowered appliance while you're away from a power socket.

WHAT TO LOOK FOR WHEN BUYING A POWER INVERTER
Apartfrom looking for a good quality well priced product there are a coupleof important elements to consider when selecting your power inverter:

HOW MUCH POWER IS ENOUGH ?
Powerinverters come in a range of power capacities so selecting the rightone for you is very important. Your power inverter needs to be able toprovide sufficient power for the equipment you want to use it with.
Here is a brief check list:
  1. Check the power consumption for the device you want to power
  2. Allow an additional 20% free board
  3. Add the power for all the devices you want to run at the same time
Note also that devices with induction electric motors like an power saw mayrequire 3 to 7 times the operating power when they start.
Usingan under-powered power inverter may damage it or the appliance you aretrying to use, so be sure to check the specific wattage requirementsand operating instructions for appliances / tools to be used.

PURE SINE WAVE INVERTERS
Normal mains power is known as Alternating Current (AC) and is a sine wave shape like the black line in the drawing below
Pure sine wave (black) versus modified sine wave (red)
Atypical power inverter produces a 'modified sine wave output' like thered line in the drawing above. While this works for most appliances,light dimmers, variable speed drills, sewing machine speed controls,some laser printers etc. will not operate correctly with a modifiedsine wave power inverter.
Pure sine wave power inverters areespecially designed to provide a more accurate sine wave output and socan be used with these appliances, but unfortunately they are moreexpensive.
Check with your with appliance manufacturer or itsspecifications to confirm if you can use a conventional power inverteror will need a pure sine wave inverter.
WARRANTY
One of thegreat things about electronic equipment is there is no moving parts(although there is a fan in some models) so you can expect a longserviceable life from a power inverter.
STANDARDS
Powerinverters generate dangerous mains voltages so ensure the product youchoose is approved for use with your mains voltage and supplier.
Powerinverters can also generate electro-magnetic radiation that caninterfere with other electronic equipment such as radios transmittersetc. Check for compliance with relevant standards such as C-Tick etc

SAFETY
Powerinverters can generate potentially lethal voltages so the utmost ofcare should be exercised using them to avoid accidental electrocution.

SUMMARY
To select your power inverter carefully check the power requirements for the appliance(s) you intend to use it with.
  1. Start power - Allow up to seven times for an induction motor
  2. Operating power - Allow a 20% margin
  3. Pure or modified sine wave

My inverter keep blowing 40 amp fuses without load


Hi Trevor,
A 1000W can barely supply 5A at 220V, less than 10A at 110V. So if a 40A fuse blows, there is a serious problem and you should not attempt to use this unit after it has been checked by a qualified person. Please be careful!

Good luck!

Can this model be used on the grid? If not, is there a sunforce inverter that can be used on the grid?


If you meant for the mains supply then it must be connected in series to the load so that in absence of power the invertor takes over and when there is power the supply takes over as it charges the battery.
So have this wiring done with the connection routed from the fuse box or main board.

Hi i have a 400w black and decker inverter as soon as i plug my lap top in to it the power light on the inverter flashs and it wont power my laptop


The output of this inverter (and most others) is a modified sine wave, which isn't quite the same as a true sine wave - like you get from a wall outlet. Unfortunately, most transformers (which is essentially what your laptop power-supply is) require a true sine-wave. Your inverter will work fine for many other 110V applications. You can buy an inverter with a true sine-wave output, but they are more expensive.

Hi , i'm sorry but i dont really understand your question , assuming the current draw is around 45 amps then 2 /0 GA is fine , just keep your leads from your panel nice and short , the connection kits are sold by sunforce and there plenty of suitable connectors on the market

Mixing different AH rated batteries, different ages of even the same type battery is a bad idea. The new batteries will be effectively reduced to the equivalent of your worst battery.

Grundfos Pump On Xantrex Modified Sine Inverter?


Look I been using solar and wind power for the last 20 years and never used public utilitiy, run your inverter to a braker box and connect your pump to it donot forgfet to ground the box and the inverter. that is all what you need...remmber modified sine wave may effect the life of the pump if it is cheep it may be ok or you need to get true Sine wave.
