February 27, 20206 yr 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
February 28, 20206 yr Lithium and no only 1 (they are 48v) Pylontech us3000 should give you same capacity you had Edited February 28, 20206 yr by Quat Allah As Shams battery name

February 28, 20206 yr Author Thanks for the information much appreciated. Where is the best place to purchase the battery with respect to price? I stay in Cape Town.
February 28, 20206 yr 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)
