Hi, I am Martien, electrical engineer, have a couple of years experience with maintenance of electrical passenger ships in the canals of Amsterdam. These ships were mostly powered with larger (up to 150kWh) lead acid batteries / Victron chargers/inverters set ups. Next I have some experiences with DIY solar systems / DIY smart EV chargers and recently with a smaller Victron Smart NG set up build and applied in a pleasure craft.
