Title: Solar charging of battery... and connectors
Post by: Supatrike on May 17, 2011, 03:34:14 AM

Forgive me if this has already been discussed (I searched the topic though).

1) Has anyone experimented with solar charging their Golden Motor battery?  I see that GM sells a solar charger, but doesn't mention if there is a charge controller required.  Can you please forward me to a thread if this has been discussed?

2) Where can I buy wire connectors (terminals?) like the ones that ship with the Magic Pie?  Or does anyone have recommendations for better/similar quick release connectors?

Thanks

Bart

I'm also interested in Q#:1... ;)

GM states Voc= 63.4V for the 36V panels, and 82.9V for the 48V panel, so it seems that it is just 3 '12V' panels for 36V, and 4 '12V' panels for 48V... (a '12V' panel have usually a Voc of 20-21V.)

no problem to charge battery with solar installation...use "boost-UP" module to increase tension from 12v to 60v (max).

i use this since 2 years in my bike.

Are you guys talking about the MPPT Boost/Charge controllers?  I have a 36V battery and I've only seen 12/24 models.

Units like this are too pricey for me:  http://www.terrapinsolar.com/Solar-Boost-SB6024HL-60A-36V-48V-input-12-24v-out-BLU-18008.htm

What sort of panel is recommended for this type of system (volt/amp or watt)?


Thanks for the info...

Also, I found a great source for replacement wire connectors - allelectronics  http://tinyurl.com/5sjfdyo

I wish they didn't already have the leads on them, but they worked great.
