Today we visited Beta Marine, to show them how we set up our largest alternator on a Beta 43. We program the alternator regulator that’s built in to our battery to suit the rev range of the engine. Beta wanted to see low power below 1000rpm. This is to protect the engine. But also has no negative affect on the propulsion of the boat. The alternator is a 190a 24v unit modified to run via the boat battery and can put out a huge 5000w of charge power.

We have been so busy this year, a lot has changed. We are in a new premises on the canal, which is perfectly suited to what we do. So much has been accomplished in moving the factory and still putting out a full work load, hence why it’s been a bit quiet on socials. Here’s a shot of our new set up.

11th and 12th of July, we are exhibiting at Electrika Show. At Brinklow. The show is all about electric propulsion canal boats. We will have our trailer there with all our battery, solar products and services. So whether you’re building a propulsion boat, need a lithium upgrade on one. Or just to see the other battery’s and solar that we have to offer come down.

A motorhome this time. This is a 560ah battery, built and installed for . Jurgen already has a 1600w solar array on the roof that we installed a few years back, but the 200ah lifepo4 battery was not quite enough for electric cooking. So we increased the capacity and installed a 3.5kva inverter. No need for LPG anymore.
