Hi Guys I do not know how to compare batteries except for the obvious duty cycles. Ritar DC12-100 Description: http://www.ritarpower.com/battery/Energy Storage Battery/DC Series/ Spec-sheet: http://www.ritarpower.com/upimg/201712415519728.pdf Ritar RA12-100 Description: http://www.ritarpower.com/battery/Reserve Power Battery/RA Series/ Spec-sheet: http://www.ritarpower.com/upimg/20177102363419.pdf I can't determine if they are both the same technology. Would anyone be kind enough to compare the two spec sheets and let me know which one is best, please? Thanks in advance for any help. EDIT: On further reading, it seems the RA keep a better charge or can run a bit longer under the same load whereas the DC is a bit weaker but can be cycled more. Is my reasoning correct? EDIT

Thanks for the replies gents, much appreciated.

Hi Guys Completely new to solar and having a hard time with solar panel selection. Equipment (This is exclusive to run a Waeco CF Fridge)... Battery: Getting a Ritar RA12-100Ah tomorrow (Please advise if I should rather get something else) Controller: Victron SmartSolar MPPT 100V/20A (Already have this) Solar Panel: I do not know! Background: I really want to make full use of the 100V/20A controller, but the higher Wp panels all have a physical size of roughly 1650 x 990mm that does not play nice with my camping trailer. 1. What is the biggest Wp panel you get that have a form factor smaller than 1660 x 990mm? 2. If I buy two smaller panels, which panels do you think pack the biggest punch form factor wise? 3. Would like them to be mono if possible. 4. If you can advise on a retailer in the Cape Town area it would be great Budget not too much of an issue, but seriously not going to pay top dollar for these fold-up solutions at 3 times the price per Wp. Unless you guys know something I don't Thanks in advance. TL:DR: Need to buy panels, want to utilize controller best as possible, form factor/physical size an issue. Prefer mono.
