Mysterious Surrette Behavior [RE-wrenches]

[Travis Creswell, Ozark Solar]

If it's 48 volt system you should be able to adjust both the inverter and
charge controller parameters accordingly and get the system online until the
replacement cell arrives.  You might be able to do it with a 24v system.

We did a set of HUP Solar One's and they are doing just fine but they are on
a 2.5 kW array and even that was less then the published amps HUP wants them
charged at.  If you ask for it, NWES will provide you the recommended
minimum charging amps for the HUP's.

I will say that Surrette will provide you with a lot of information.  They
have a technical bulletin for just about anything you could imagine.

What about the Absoltye IIP?  Any experience with them?  I'm putting
together two jobs right now that are going to need a "serious" battery and
regular maintenance could be an issue.

Travis, Rob, Dave, & All;

An interesting thread, considering I returned last night after 
installing a new set of Rolls Series 5000s to have the inverter shut off 
as soon as I plugged my sawzall in to the customer's new system. 1 cell 
was completely Dead (0 volts) and since I've been moving to single 
strings to avoid paralleling, the system is inoperable. So what is the 
current word on Rolls? I'm beginning to wonder, after reading everyones' 
experiences with them.
What is a better battery? I sold Bulldogs and Exides before, and those 
were all fork lift batteries without apologies. I found the Rolls easier 
to install, and easier to get cycle life data on. I'm sure not going 
back to L16s.
