At my larger solar sites where a 5-10A battery charger just isn’t enough, I have had good success with the Tycon 65V 1200W AC-DC power supply (PSVHP-65-1200) fed into a different MPPT controller, hooked to the batteries in parallel with the other PV controller. Into my 24V string, I generally get around 38A charging while it’s running, resulting in good “fuel use efficiency”.
At smaller solar sites, I have used a Tycon 300W charger (kinda bulky) or a Deep Sea Electronics DIN rail charger. Generally, if your battery string is wired for 24V, any high amperage constant current limiting 48V power supply into an MPPT solar controller makes a great charger for running on a generator. If you’re 48V, it seems to be harder to find an economical 60+V high amperage constant current limiting power supply, but the Tycon above seems to be decent.
