Another option is to install larger batteries and an inverter - suitable
for limited power needs, but otherwise nice.
(Running a 600 W microwave for 10 minutes will draw 80 A from a 12 V
battery for 10 minutes, ie some 12 Ah).
Depending on your needs this can be a good option. And cheaper as well.
Works well for me.
