Im on a first time self build project . I plan to be off grid mostly for fairly long periods(based in Scotland) I am looking to buy a 2000w -3000w generator and possibly a solar panel for the roof at about 160w I would probably be looking at getting 2 x 12v batteries at least 190ah each .
Does this seem like a good setup , i will have an electric hot water shower installed as well as a fridge and possible tv , 3 phones to charge and normal daily usage etc .
Does a generator charge the batteries and can it all be hooked up to one system . How do i switch between solar and generator .. do i meed a special control board ?

250 w of solar and a mppt regulator which charges cab batteies and one ah to starter batt,do use a outside jack for genny and there will be know probs as it will run either the on board 12v charger and also into consumer unit for 230v.
I would also use a mains inline phase changer incase you want to use hook up and find it wired wrong way round<happens a lot on european camp sites.
Also use a good smart charger like a numax or similar .
The will be no prob with solar or genny working with each other,also remember some usb and cigy ports plus a volt meter & fuse box,if using a inverter remeber a change over switch plus a remote switch for lights at night when in bed ,good luck with build.

genny is far too small ....you need to work out the start up power usage ie a tv ...start up power 1100w.....then switches to using 100w ....so get the biggest one you can also im doing the same as in off grid all year round at 2 batterys arnt going to be enough ....im heading into using 6 2v at 490ap then a 2800w genny ....price around 2k just for a start and knowing scotland i personally wouldnt bother with sola power .....wind power best way .....what part you abiding in mannie ?
