inverters any recommendations

[scouse272]

hi all
been looking round the forum and it seems to me that if i don't use an ehu i'll have to get a couple of batteries and a b2b charger,any recommendations for inverters

thanks

Really depends on your needs. We have a small leisure battery and it can go for about 3 days without a charge. We just added a split charge relay and as we drive every day when we are away that will be enough for us to run the lights, charge mobile phones and tablets and run the water pump... which is all we have fitted

want to run a telly/dvd player so was thinking 2 110ah batts and b2b sterling charger but the inverter should it be pure sine or modified sine wave


thanks

I think you are better off with a 12 TV from what I gather the cost of a pure sine is prohibitive and the modified sine can damage the set... but I've not got one as we use the tablets and tinterweb

If you are only thinking of TV and dvd then get 12v, you don't need an inverter. We have a 1500w inverter to run hairdrier, kettle, microwave etc but TV is 12v.

it probably won't be just a telly.laptop various chargers etc so maybe a 1000w inverter just in case i need it for anything else,will probably be off ehu about 50% of the time

Agree with comments about using 12v where possible, for an inverter think about what you want to run off it and don't go too much bigger than you actually need and I would say go for pure sine wave although they are more expensive.

Don't forget that the inverter can take a lot out of your batteries depending what you are running off it, amps from your battery is roughly watts divided by volts, for example 1200 watts from the inverter would take 100 amps from the battery plus a bit more for efficiency losses.

yes i know what your saying but if i'm off ehu i can charge the batteries off the engine
