Paul Pryor
Hi all my name is Paul Pryor, I have a 43 ft. steel cruiser called "Rumba" we have owned her for 23 years and after using various auto electricians.
I was introduced about 7 years ago to Steve from Sweens auto electrical. Steve and I installed 1400 watts of solar and a Victron Solar controller, and 6 x 12-volt Revolution Lithium LiFePo4 Deep Cycle Batteries plus a 3000 Victron Quatro invertor - charger, plus a 50-amp Victron charger. 2 x DC/DC Chargers from the start batteries.
He also installed an Electrolux 3000-watts and 240 volts alternator all running through the Victron control system. I have a 5.8 Kw Westerbeck Genset, and a Deep-Sea Electronics Auto start for the genset. Steve rewired the boat, and everything has worked better than we expected for the last 7 years we have lived on the boat not in a marina everything runs on 240 volts.
The best part of using a quality business to design supply and install is the after sales service and the knowledge that if anything goes wrong or you don't understand everything there is someone to call Steve has never let me down.
Cameron Burke - Burke Constructions
We have used Steve for marine electrical for a couple of years now and love Steve's professional and very knowledgeable approach to all jobs aboard our vessel.
We recently undertook a solar upgrade with 1200 watts of new panels installed along with new chargers, inverter and lithium battery bank.
This has been a game changers for us and wouldn't have be able to do it without Steve's ideas and approach to the job.
Thanks Steve.
Marcus and Jo Byrne
Steve installed the electrical system on our sailing catamaran. His expertise and product knowledge meant that we did not have to provide
him with an electrical design; a big saving.
As owner builders, we were able to assist Steve with running cables through the hulls - another saving. Steve's experience in the boating industry enabled him to make recommendations which we hadn't thought of, and which resulted in an excellent outcome for our vessel.
Examples of his tips are:
- change our house bank from 12v to 24v
- install larger solar panels, not a hydro-generator
- install a separate freezer and an air conditioner
- change our cooking appliances from gas to electric.
Thanks Steve.
