Lititure on how to add a generator to a solar system


Happy Breffast!
Your Samlex inverter does not appear to have a charger function.

You simply need to get a charger that's capable of converting AC to DC with suitable charge voltages.

Will lists some chargers here:

Any 12V charger that charges to 14.2-14.6V will work. Float is not needed, but if it's an option, it should be set to 13.6V or less.

Pick the charger based on the amount of time you want to recharge, i.e., assuming you have discharged down to 20%, you need to add 160Ah to your batteries.

10A charger would take 16 hours
20A charger would take 8 hours
40A charger would take 4 hours

Times are approximate.
