HELP! SOLAR SYSTEM ON RV NOT CHARGING BATTERY
[FONT="]Any suggestions to make work properly are appreciated.[/FONT]
[FONT="]My system is a Go Power 155 watt solar panel and a Go Power GP-Gpm-30 Regulator. By the way Go Power has just came out with the 155 watt so the instructions for the 145 watt are the same. http://gpelectric.com/products/145-watt-solar-charging-kit[/FONT]

[FONT="]My readings on 8/24 no sun were 12.3 V 74% and 0.0 Amps[/FONT]
[FONT="] on 8/25 no sun were 12.1 V 72% and 0.0 Amps[/FONT]
[FONT="] on 8/26 sunny were 12.2 V 70% and 0.0 Amps[/FONT]

[FONT="]I took the following readings with my meter:[/FONT]
[FONT="] [/FONT]
[FONT="]On regulator at solar connections with battery terminals connected to regulator and battery – 19.67. Readings on solar connections with battery wires disconnected were 19.59.[/FONT]
[FONT="] [/FONT]
[FONT="]On regulator terminals at battery terminals with battery wires connected 1.36. With battery wires disconnected 1.36.[/FONT]
[FONT="] [/FONT]
[FONT="]At battery with wires connected to battery terminal on regulator 12.25. With wires from battery terminals connected on regulator and disconnected at battery 1.35[/FONT]

[FONT="]I have two 12 volt Sterling 24RV-90 Deep Cell Flooded batteries which both say 14.4 Hours @ 5 amps and 590 CA and 460 CCA with 125 reserve. Per Go Power the positive is connected to the positive on one battery and the negative is connected to the negative on the second battery.[/FONT]

[FONT="]The install was by a friend who is an electrician who has since rechecked all connections and the crimping at the battery. Also we used the # 8 wire that came with the panel. The panel wires are 5 foot from the regulator and the wire from the regulator to the battery is 17 feet. We understood the instructions to say double the wires and then cut in half we ended up having to splice 5 feet away from the battery with the same wire. The slices are solid and checked and same readings at the splice as at the battery and the regulator 12.25.[/FONT]

[FONT="]If anyone can tell me what we may had done wrong or what to do or check next I would greatly appreciate it.[/FONT]
