Generator for Battery Charger

Well i plug my 4 stage 16 - 25amp/hr charger into my yamaha and it works fine for the batteries.

But mines a yamaha with the pure sine waver inverter.

Spose it comes down to whether the cr#ppy square waver inverter on cheap gennies might hurt your, if you have one, sophisticated electronic battery charger.

If you are only charging a standard type car battery or similar then this genny would be ok provided you purchased a simple (read cheap) battery charger also. Just give the battery a 2hr charge each day or something similar depends on your usage.
Then again if you can rake up the cash a folding 80watt solar panel such as the projecta one that repco sells would be the best method.

If using a generator to charge batteries I have heard it also pays to plug something with low draw into the AC outlet - perhaps a low wattage light globe on a 'made up' wire and plug. Apparentl;y it helps to stabilise the engine revs. Some battery chargers won't kick in the load actuator.

Used my GMC charger for about 3 years with a cheap 4 amp charger with no problems. Helps to load it up with a 100 watt lamp to keep the genny from hunting.
Would never use it on my smart charger though and bought a 1 kv Honda for that.
