Introduction

Hello,I just joined the group and am looking forward to learning about electric conversions.My wife, Myra, and I have sailed for the past 30 years and currently own a Morgan OI 28.  Spirit still has the original Volvo MD-7A, but the next time the engine requires more than oil, diesel or filters, the electric conversion will begin.  For now I will keep quiet and read all the info on the forums. Glad to be here,CarlSee More

Introduction

Hello,I'm Doug and I just discovered this forum and its wealth of info. I've been active in the EV car world for 4 years now, and have continually watched the marine industry make its inroads with electric propulsion over the past several years. I think I'm ready to make the commitment to electric for my Nonsuch 30 "Such is Life"  currently moored in Anacortes, Wa... but soon to relocate in Everett Wa.Having her closer to home will allow this type of major retrofit to happen. The goal is to…See More

Newish Solidnav user seeking a bit of solar help

Our Cal 2-27 came equipped with a Solidnav drive from the previous owner. Over the few months we have owned the boat I've come to really love the drive. Where I'm running into an issue is with figuring out a solar set up. I may own an all electric boat, but I am far from electric savvy.Yesterday I spoke with BlueSky about an MPPT and it wasn't a productive discussion. Our battery bank is built around four AGM batts. While I understand the drive requires 48v, what decisions does this force as…See More
