We stopped by AM Solar in Springfield Oregon after Alumafandango last week.
They installed two GS-100 panels on the road side and one GS-135 on the curb side. A replacement low profile bath vent needed to be installed to accommodate the GS-100 on the left rear.
They replaced the two OEM Interstate Marine/RV 12 volt
batteries with two true deep cycle Lifeline GPL-4CT-2V 220ah AGM batteries. The battery box height needed to be extended 2 inches.
A fourth panel could be installed if the TV bat wing were replaced by a smaller antenna. I'm not sure that we would do that without first installing two additional AGMs. I'm a little concerned about adding another 157 pounds of batteries and panel near the front of the trailer. We're pretty close on tongue weight. So we'll see how it goes with 325 watts and two 220ah AGMs.
AM Solar and their installer Marvin of Precision RV Service installed the system in one day. We met Marvin and the AM crew the day before for a pre walk thru preparation. They did a great job. Marvin is very thorough and excellent at explaining all aspect of the system.
He recommended that we replace the OEM Charger/Converter with a 4-Stage Inteli-Power 4600 unit (AM was out of stock). The multi-stage vs. OEM single stage unit would be much kinder to the very expensive AGM batteries.
