Re: [RE-wrenches] Outback FM - was High-power MPPT/Charge Controllers?

[Allan Sindelar]

The latest Outback product guide very specifically identifies the maximum PV wattage for the FM60 and 80 at each nominal voltage. But I see it's also in their website (middle column FM80, right column FM60): Maximum Solar Array STC Nameplate 12 VDC systems 1250 Watts / 24 VDC systems 2500 Watts / 48 VDC systems 5000 Watts / 60 VDC systems 6250 Watts 12 VDC systems 900 Watts / 24 VDC systems 1800 Watts / 48 VDC systems 3600 Watts / 60 VDC Systems 4500 Watts NEC Recommended Solar Array STC Nameplate 12 VDC systems 1000 Watts / 24 VDC systems 2000 Watts / 48 VDC systems 4000 Watts / 60 VDC Systems 5000 Watts 12 VDC systems 750 Watts / 24 VDC systems 1500 Watts / 48 VDC systems 3000 Watts / 60 VDC Systems 3750 Watts Allan Allan Sindelar al...@positiveenergysolar.com NABCEP Certified Photovoltaic Installer NABCEP Certified Technical Sales Professional New Mexico EE98J Journeyman Electrician Positive Energy, Inc. 3201 Calle Marie Santa Fe, New Mexico 87507 505 424-1112 www.positiveenergysolar.com On 11/19/2011 9:17 PM, maver...@mavericksolar.com wrote: Wow! The most I have in one Outback install is 8 MX60s and 8 VFX3648s. Overall the customer has been happy with the performance and the stacking power save feature helps with idle power draw.  As for the OPs request, the most PV still remains to be about 5000 watts gross power per controller (80A x 50V / 0.80), even if they slice it up as high voltage or not high voltage type controller.  Another curious idea is the cost per volt when comparing 150V input, 80A Output controllers to the new high voltage input controllers. That cost consideration spreadsheet is still under construction. Thank you, Maverick Maverick Brown BSEET, NABCEP Certified Solar PV Installer ® President & CEO Maverick Solar Enterprises, Inc.

High-voltage DC input (up to 300Vdc) preferred.  Units will connect to a 20-24 kW PV array and 150 kW-h battery for a large off-grid system. Not locked into 48Vdc.  Can go up to 108Vdc (nominal) if needed. Any such CC units available? If not, what's been the collective Wrench experience in paralleling multiple controllers of whatever max output amperage exists on the market?  I realize a paralleled configuration of this nature would entail multiple separate arrays in use on the input.  That won't be a problem.  Just need to be able to feed the common battery bank. Thanks.
