EPV Solar EVP-54 The Isc is 1.49 A
The cut sheet does not list a series fuse rating for the module. But it does say something about being able to use up to 8 in parallel without external protection. I am in the hunt for installation instructions. - Peter Peter T.

Fronius has a white paper explaining when series fusing is required and when you can get by without.......it all relates to series fuse rating and Isc......the higher the series fuse rating and the lower the Isc the more strings you can parallel with out adding series fusing........ -- Sunny Regards, Kirpal Khalsa NABCEP Certified Solar PV Installer Renewable Energy Systems www.oregonsolarworks.com 541-218-0201 m 541-592-3958 o On Tue, Jul 21, 2009 at 2:44 PM, Peter Parrish <peter.parr...@calsolareng.com> wrote: We are doing an engineering design for a large scale PV ground mount system based on a-Si modules. Since the Isc of the modules is 1.5 A, instead of 7-8 A of typical c-Si modules, are there special low-current combiners out there? Does each string need an overcurrent protection device? Any help with a-Si based system design would be greatly appreciated. Peter T.
