Rolf Posted February 27, 2020 Share Posted February 27, 2020 Hi I have 4 Monbat 180ah Deep cycle Batteries 12MVR180 connected to a 5kva (48v) Mercer inverter. The batteries have not held a charge for a few years now and I only use them so the solar system works. I now want to replace them with new batteries and need advice on what batteries to buy, lead acid or lithium? If I go lithium do I still need 4? Regards Rolf Quote Link to comment Share on other sites More sharing options...
SYC Posted February 28, 2020 Share Posted February 28, 2020 (edited) Lithium and no only 1 (they are 48v) Pylontech us3000 should give you same capacity you had Edited February 28, 2020 by Quat Allah As Shams battery name Quote Link to comment Share on other sites More sharing options...

TheJoker Posted February 28, 2020 Share Posted February 28, 2020 Most places are sold out atm, I got one delivered to me in Cape Town yesterday from Sonop Solar in Citrusdal. They might still have some left of the stock they received yesterday. Paid them and received 9 x in total, delivered to my door. (Delivery charged for) Quote Link to comment Share on other sites More sharing options...
