July 27, 20223 yr Hi, I want to replace my 3 year old entry Mecer 1400W 24V setup. I just need a backup system that can deliver ~1kW for 2.5h. So I'm thinking a 3kW or 5kW inverter will do? With what battery(ies)? Any recommendations on value for Rands right now?
July 27, 20223 yr For future proofing if budget allows definitely aim for 48 volt system with lifepo4 battery/batteries.
July 28, 20223 yr Author Thanks @WannabeSolarSparky any recommendation for an entry-level but good 48V LiFePO4 system?
July 28, 20223 yr Hi Deonvaa, I would recommend a 5.6kW OGS5.6 inverter made by Voltronics & marketed by Kodak. Pair this to a 5kWh Livoltek BLF51-5 Lithium Iron Phosphate battery. I'm not sure of your budget so I'm actually recommending what I would use & what I would recommend if providing a consultation for someone. The sub 5kW inverters unfortunately I have found to have lots of clones & also are 24V systems which I'm not fond of at all. The 48V system is just safer with less amps pulled & smaller cables to work with. However, please don't let me tell you that this is the be all & end all of suggestions. Many guys know the sub 5kW market much better than me.
