Oceanvolt references

I am looking at buying 2 SD15 KW saildrives, 8 LiFePO4 batteries, 2 14KW DC Diesel Gensets and a solar charger/controller from Oceanvolt. They provided several references of people who had their systems in catamarans so I contacted all of them. Every one had a good story to tell! Sure there were a few problems, but the owners all said that Oceanvolt support was impressive. Does anyone in this group have a history with Oceanvolt?See More

Sea Trials Continued

Solar sailing down the Fraser almost making power.  Coming back upstream was interesting as we had to make prop for 50 amps a side so 100amps minus solar so 85amp deficit more or less to obtain our 7km/h upstream against probably 5 knots of current.https://youtu.be/rEA-u3lZqVg…See More
