Finally a significant design option/upgrade from Xantrex for their eGEN battery-electric system. It’s called FREEDOM eGEN MAX.
Over three years ago Xantrex introduced the original eGEN battery-electric system based on 12V, 600 Amp-hour LiFePO4 batteries, and 3,000-Watt inverter/charger. This was a cheaper option to Volta design and was quickly adopted by various Class B van manufacturers.
Xantrex recently announced a higher capacity system marketed towards larger motorhomes, although I suppose it could be installed in van campers also. The new system is available in 12V, 24V, and 48V, with 48V appearing to be their main focus.
Brochure shows a new EX 4,000-Watt 48 VDC inverter/charger with 90 Amps of battery charging capability (equivalent to 360 Amps at 12 VDC), allowing for fast battery charging to capitalize on lithium technology.
The brochure also makes reference to 48 VDC X 300 Amp-hour battery, equivalent to 1,200 Amp-hours if at 12 VDC. That’s roughly twice the size of original 600 Ah eGEN batteries used in vans, so should better support Class A and C motorhomes.
Thoughts on larger “MAX” system? Personally, I’m happy to see Xantrex finally offer a 48V system. It was about time.
