I have been using Growatt SC48120-MPV stand alone charge controllers and they have performed adaquately. They have a max solar pv input voltage of 250v. I bought them in a special one time sale so I found them a good value at the time. It is nice that they have two separate PV string inputs are 250v each.
The new system I am setting up is 15kw of 270 watt panels and life would be made a lot easier with a higher input pv voltage, ideally 500v plus (up to 1000v). I do not use combined inverter/charge controller systems so am looking for any makes of stand alone charge controllers with that higher input voltages. I generally prefer cheaper chinese off brands. The system is very rural and I need full redundancy in every component anyway. I have had laughable experiences with even the top tier makers in terms of honoring warranties so I don't care about that at all.
There does not seem to be any easy way of searching by max input voltage so any pointers on brands/makes would be very helpful.
Looking for devices that can charge a 48v battery bus.
