[QUOTE="chrisc, post: 915366, member: 746"] Gel batteries are more reliable, but the discharge cycle of all lead-acid batteries is very shallow and all are easily damaged by too deep discharge and high current charging I calculated (or should I say it was done for me) that I would need 12 x 105 a/h batteries to supply 230 VAC at 300 watts for 3 hours (that is a 12 amp current draw). For that price I would get a 3000 watt/hour lithium ion battery. Less than 5% of the size of 12 batteries, can cope with deep discharge cycles 105 a/hs are currently R1700, if you can get them (no-one in Cape Town has) so 12 x R1700 = R 20400. Same price as a lithium-ion battery [/QUOTE]
