I have 500 panel watts, a Morningstar TS-45 (PWM), 2000 watt inverter and four 6 year old T105s. I purchased three 100ah SOKs to replace the tired T105s. I now have discovered setting the controller up for lithium is not as straight forward as one would expect. Is that possible? If so, should I carry on and do it or should I invest some money to purchase a Victron and monitor? I would prefer to not do that and purchase more panels instead. I'm thinking 300 more panle watts would put me close to the capacity of the controller. Probably get a Victron controller and monitor next year?
