neighbors sharing PV charge [RE-wrenches]

[Rainshadow]

Howdy wrenches,

Does anyone have any experience with using a single PV array to charge two somewhat distantly separated battery banks?  We built a system for a weekend cabin up here last year and now the guy's neighbor wants to install his own battery and inverter system but tie in to the existing array for charging.  There is room on the rack to expand to cover both their needs and it would be difficult to site a new array for neighbor #2.  They are good friends and want to share resources.

I thought about using the C-40 in load control mode to float battery #1 and then dump the charging current to another C-40 at battery #2.  But it seems like there might be a better solution.

Its a 48V system and the distances are reasonable, so voltage drop should not be a concern.

Any suggestions?  Thanks,

Eric Youngren
