Hi, Nate! Thank you so much for the care and detail of your blogs/vids. I am looking to upgrade/replace electrical in my 2004 Prowler (30amp). I will primarily be on shore power and would like to purchase separate components. Generally, do I need a convertor charger, automatic transfer switch and pure sine wave invertor?

Hey Nate, Amazing site and YouTube channel. I took your advice and purchased from your site all the products except 2 things. My Victron 12v /3000w / 120 inverters. So how do I wire them up together?

Hi Nate - I have your 12v wiring diagram- and im having a problem with a simple wiring install; all my 12V overhead lights i want on a dimmer (with on /off) and a simple on / off switch in another location. I followed your diagram- but it is still not working. could this be the type/ model of switch on these LED lights? any help would be great- thanks

Happy New Year! My planning is still in the infant stages for setting up a system for my utility trailer for work lights and a charging station for small electronics and equipment batteries. Your tutorials, spread sheets, and calculator tools have been very helpful. I would like to also incorporate a small gasoline generator into the system which leads to the question of does the controller equipment require an inverter generator or would a non-inverter generator be ok? It would not be good to install a system only to find out a non-inverter generator fries the controller and inverter electronics.

Thank you,
