Backup Generator Charger (slrpnk.net)

Can anyone recommend a charger (or type of charger) to use for recharging a 24v lead acid leisure battery bank from a backup generator? Currently we have a cheap charger bought online but it only puts out about 130 watts, which means running it for quite a long time to significantly recharge the batteries and is much less than gets fed to them when the sun shines. TIA

It definitely has. But in my case, I'm not bypassing it - the external part of the charger is communicating to the car using the Type 1 interface and telling "charge at X amps". (But I know that's not applicable to DIY situations.)

...and since the tripping occurs within the ramp-up period or very soon after (e.g. on second 7), I'm fairly certain nothing has managed to overheat yet. I think that some generators have poor steering regulators, mine included.
