I currently have a modified sine wave mecer 24v unit with two 105ah Royal batteries. It has been working well. I also added a 75/15 Victron MPPT and 405w solar panel and this keeps the batteries fairly charged during LS. However, I want to upgrade to a PSW system with the same batteries and solar setup mostly as I do have some concerns regarding the long term use of MSW. My load so far is about 350-400w. Bearing in mind my current setup, I would appreciate any advice on what would be a good upgrade. I am considering the Victron multiplus 24/500/10/16 or the 800 version as I may want to increase the load a bit.
What would you guys recommend? Also will the PSW work much more efficiently than the MSW so for example although the power specs of the Mecer is 1440w will a Victron PSW inverter at say 800w or 500w be pretty close or comparable to the Mecer. Appreciate feedback
