H33C Electrical Update - 2013
Home Up

In 2012 I installed 450 Ah of house battery and a cranking battery.  this year I added the solar panels, Blue Sky charge controller, XANTREX PROWATT SW2000 2000W TRUE SINEWAVE INVERTER, Xantrex 15A automatic transfer relay switch, and Victron 602S battery monitor.  The solar panels are written up separately, and the installation procedure for all the items are nothing special.  The picture below shows the batteries being charged in float mode (13.26v).  If it were in accumulate mode, the voltage would be around 14.1v.  I have yet to install the second battery bank monitor.  All I need to do is attach the monitor lead but it was a bit short and I want to verify the correct way to splice the wire.  It appears to have a means by which to extend the cable so I thought to check that out before I cut and slice in another length.  The Blue Sky 1215i charge controller it hooked up standard (+/- for the battery bank, +/- for the panels).  The automatic transfer relay switch enabled me to use shore power or battery/inverter to power the outlets in my system.  If connected to shore; outlets draw from shore.  If not, outlets draw from batteries/inverter.  Automated beauty.

 

I have some more pictures to take for the inverter, transfer switch, and wiring for the solar panels.  Until I do the stock vendor write-ups and photos will need to do.  Refer to http://svhotwire.com/sopray-solar-panels/  for the solar panels (140 W Sopray panels picked up in the 2012 Annapolis Sailboat show).  They are hot items so most places are out of stock with them.  Contact SVHotWire for availability.  The price last fall was $275 per panel.

    I have the switch but do not think it is needed at this point.

     

    The transfer Relay is shown below.  On the H33 there are two 110 runs (one to the head, one along the port side).  I combine these runs on the output side of the relay.  The input connects to where the 110 circuits were wired in the panel. This protects the switch with a 15 Amp breaker.  Also when ever shore power connected, outlets powered by shore.  When show power removed, the outlets are powered by battery/inverter.  Its all good and works like a champ.

    An easy to mount 15A Inline Transfer Relay provides switching between shorepower and inverter AC source. It comes with a power plug for convenient connection to the inverter GFCI and a hardwire cord for the AC input and output interface. It is available as an accessory to the Prowatt SW product line.
