[Dana Orzel]

I have a 48 V system at my home and I have an older son Frost 24 V DC battery based freezer that is supported by a IOTA battery charger power supply it’s worked flawlessly since the day I put it together nearly 22 years ago the IOTA chargers come in a variety of sizes depending on your needs

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.  Thank you.
