Re: [RE-wrenches] questions about solar charging 72v UPS
HI all I check into the Tristar and it connects the same as the Outback, what I could not remember was the set up and communications cableing. The set up relies on the negative floating and in this case, the MS software and a Laptop, sets the 36 volt charging profile, the communications port is isolated from solar negative. This is true for the Tristar and Tristar MPPT Darryl Need Mail bonding? Go to the Yahoo! Mail QA for great tips from Yahoo!

Re: [RE-wrenches] questions about solar charging 72v UPS
I see the FM60 had a 60 volt option. Why not just use a single one at that battery setting for charging the battery bank?

The upper voltage 36 to 72 volt CC can not have a communication line connected, it will blow something, either the hub, or the controller as the controller floats but the communication lines are connected to the negative, and it would be 36 volts above ground.

Re: [RE-wrenches] questions about solar charging 72v UPS
the post I responded to started with was the 72 volt nom battery pack charging off from solar. the solution involved using two chager controllers in series, charging off the array in sort of a bipolar fashion. I used this series chargers to charge a lead Sled 72 volt car in my dark past. The 72 volt battery would involve almost 90 volts to equalize.

Re: [RE-wrenches] questions about solar charging 72v UPS
Hi all I have charged 72 volts on a golf cart type deal, with 2 each morningstar T60 and with 2 each MX 60s But Appolo may work or Classic the trick is only use the charging function do not connect any communication cables Grounding is the problem. as one of the controllers is floating. with its negative terminal at 36 volts. The array has to be set up bipolar. The MX 60 was done with help from the old Outback Crew, back when Chris and Bob were there. I do not know who you would speak to now. With Morning Star you have to have the meter for the t-60 to set it up for 36 volts again check with MorningStar, I can not give you a name. I only now work with Brad Connect a center tap to the batteries 36 volts connect negative of one controller to negative of array, connect Positive to 36 volt point of batery. connect second controller negative to 36 point of battery and positive to 72 volt point. Also the MX 60 may have changed. the Tri60 may have changed.

That's about the only option I know of. Even though the HV controller from Apollo can accept a similar range of PV input voltage I think that unit stops at a 48v battery--maybe because of code problems with battery strings above 50 volts. For charging a 72 volt lead battery, consider a minimum of 36 X 6 = 216 PV cells in each charging string. Confirm that cell count suggestion with someone who knows more than I do about the Midnite controllers...such as boB Gudgel who is a frequent List contributor. I just unboxed my first Classic controller and I look forward to learning more about this item. With a 72 volt lead acid battery bank it will be difficult to maintain equal state of charge on the 36 chemical cells in each battery string. As you know, Ron, one can only add/remove energy through the whole battery string--barring new developments--so if some of those critters get out of line it will be tough to re-establish good discipline.
