<\/a><\/p>\nThe panels I decided to add are from Global Solar<\/a>. I ordered from the parts department at Safari Condo<\/a>. They use them in their Alto trailers.<\/p>\n In preparing for the upgrade I researched wire size, controllers, etc. and decided on 10 gauge wire, connecting all 3 panels in parallel.<\/p>\n Since I had already replaced the original wiring with 12 gauge wiring I decided to leave that in place and use new #10 wiring for the 2 100 watt panels.<\/p>\n Actual installation turned out to be easier that expected. Perhaps the time spent on preparation paid off at the end. <\/p>\n Going to leave it connected with a temporary 50 foot harness to confirm all is well before drilling holes in the trailer. I see about 13-13.2 volts inside my garage when sun is bright and with fluorescents on. Currently using PVM controller but will be upgrading to Renogy MPPT controller before making the installation permanent.<\/p>\n <\/p>\n Update: Jan 27\/19:<\/strong><\/p>\n Bit the bullet and drilled the holes to get the leads inside. <\/p>\n Taking a bit of a risk by relying mostly on cable insulation to protect going through roof. Didn’t want the normal bulky covers as it’s always in view. <\/p>\n Since there is no harm in shorting the panel I went this route. I can always go to the bulky\/ugly later on if it becomes necessary. I’ll be fusing each 100 watt panel separately. Since the 40 watt is original I’ll leave it as is, unfused.<\/p>\n While waiting for fuses I installed the Renogy Rover MPPT controller. My first choice is to install on top of cover that encloses the power\/fuse panel and charger. <\/p>\n I’ll be installing a temperature monitor to keep an eye on heat and if it looks like a problem it’ll be relocated towards the front of the compartment. Same goes if noise is a problem.<\/p>\n <\/p>\n Updated Feb 14, 2019:<\/strong><\/p>\n Changing from the Renogy controller to a Victron MPPT. It is smaller in size and will allow for a better mounting location.<\/p>\n Also changing to serial connection for the 2 100 watt panels. Turned out that wiring would be a bit more simplified.<\/p>\n Updated Feb 15, 2019:<\/strong><\/p>\n Victron 30 Amp MPPT in place. <\/p>\n Still a work-in-progress but since we’re still in winter mode… no rush.<\/p>\n Mounting plate is 1\/2 inch plywood glued to side wall using construction cement and usually 2 screws to hold it in place while glue dries.<\/p>\n <\/p>\n <\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a>Not ideal spot for heat dissipation or possible noise as one sleeps right above it.<\/p>\n<\/a><\/p>\n
