He wants to upgrade his array, inverter and battery bank. There are no options for inverter/chargers over 4000 watts in 24v dc. The same goes for lithium iron batteries. Everything (of higher wattage and battery capacity) seems to be in 48v only now. If going to 48 volts how do I acomodate the few but important 24v DC loads in the home. Is a 48v to 24v step down converter the best option? What do you think? Any help would be appreciated.
