I can get a set of 24 x 2V cells for R53,000 (New) which includes all the connectors and a watering system. The cells are First National MTL19XF 585A/h. In underground conditions these batteries last for 5 years plus in very harsh conditions. I know of someone with a similar set on his farm that have been running now for 25 years powering ,fridges, lights and security systems.
Will Pylontech work with my Mercer inverters? I doubt that Pylontech will be cheaper for the same A/h.
