   Snoozing of course means that there is not enough PV input power to do any useful charging and to wait another 5 minutes and try again.  That's what I had it doing when it was the MX60 anyway.  So, if the FETs blew, seeing snoozing for a while could make sense. You didn't CC the others, Dan, if you had meant to. Thanks ! boB  On 1/7/2019 1:06 PM, d...@foxfire-energy.com wrote: An update..

Makes no sense that a LiFe BMS would harm a charge controller like the FM60 (or other MPPT CC) UNLESS it maybe all of a sudden SHORTED the output of the CC while it would putting out high power at high PV input voltage...  I wonder why OB says this is common ?  I know they didn't say it was "common" exactly but that's what I get out of it.

Howie,

We have many hundreds of Li battery systems sold and installed. Never had any 
failure of PV controllers including Outback due to charging Li-ion.

Re: [RE-wrenches] Racking questions

[Ray]

It looks like Everest racking, but is a slightly different profile than 
what they are currently making. The hardware is similar (heavy hex head 
bolts) but also different. It could be a totally different brand I've 
never seen though.  If its Everest, I have some misc parts, but no 
rails.  They definitely have a tilt option that I've used and was happy 
with.

and don't recognize the rack brand shown in the two attached photos, 
so I am asking for assistance.


What is the brand of rack?

The existing array is set at 30º, and at our 36º latitude it should be 
set at 40-45º for better winter gain. Can you suggest the specific 
model of fixed or adjustable back leg to raise these six modules up?


Thank you, Allan
