hi folks ..after reading loads on the forums ..i was wandering if anyone could recomend a good allround inverter ..does not have to be pure sine wave ..but the gen seems think and work out what you need and double it ..so i am looking at 2000watt to 2500... price is important to ..but also want something that will last a while ..also can anyone tell me can you mix batterys..ie can you have forklift battery and add on truck batterys ..as i have an unlimited supply of truck batterys..or should i just use one or the other ..thanks steve g

Are you looking for just the inverter, or an inverter with a charger built in?  What will the primary energy sources be?

..also can anyone tell me can you mix batterys..ie can you have forklift battery and add on truck batterys ..as i have an unlimited supply of truck batterys..or should i just use one or the other ..thanks steve g

Not in the same battery bank!  Not only should you not mix different types of batteries but you shouldn't even mix the same type of batteries with differing ages.

just the inverter i think ..as the windy has its own charge controller and so does the pv ...but would have liked a controler that could have done the wind and the solar instead of ..i have found one for sale for windmill ..ie controller that also has input for solar pv 110 ..is it worth getting ?i want to keep cost to minimum ..but not to the degree that it only lasts a few months ..i wont be running more than a 1000watt at max ..n ow running about 200watt..

I think I am missing some important part of your set up.

You use 200w & want to use 1000w
your solar is 180w
your turbine is 500w

As the wind is unreliable I assume your MAX charging per day from the solar is 720wh (4 hours peak x 180w) in summer & about 1/4 of that in winter. That converts to about 500wh per day into the batteries. So you could use your 1000w for about 30 mins per day (or your current 200w for 2.5 hours).

The inverters that come with built in chargers are only for charging with an AC source, like a generator.  Even with an inverter/charger you'd still need a separate charge controller for solar and wind.  What do you plan to do when there's no wind or sun?

...but would have liked a controler that could have done the wind and the solar instead of ..i have found one for sale for windmill ..ie controller that also has input for solar pv 110 ..is it worth getting ?
I'm not familiar with charge controllers than can do both wind and solar _at the same time_.  Are you sure it's not an either/or type setup?  Do you have the make model to hand?

oh well, if people won't remove spam when politely requested.................. whistlie

I followed the link to find that a certain company is based in Newark - as any of the "old timers" on the site will know, Newark is the address of one of the biggest scammers in renewables going - innumerable companies starting up and disappearing, often with client's funds......... surely no connection........... whistlie

Pity, looked like a great deal on the turbine: a 1kW rated turbine at 8m/s with a 3m diameter rotor for 370 quid.  Never seen that before.
Steve, your solar panel was indeed quite a bargain at 2.2 pounds per watt!  Again, never seen a price like that for just 1 panel.
