I bought a 5875 package from Ziller and bought the battery from them also. I am getting close to getting my wiring done and thought I would get the battery installed and get the genny activated and run it in manual. Well, my battery, a Ready Power brand, won't fit in the enclosure. Anyone else ran into this issue? Thanks.

I think I found what the problem is. The battery specification in the manual for your generator is a [U]Group 26[COLOR=Red][B]R[/B][/COLOR][/U] which has the terminals in opposite positions from a Group 26 battery. That would make a difference when connecting it to the cables. You may need to get the battery swapped out by Ziller. Give them a call on Monday morning and I'm sure they will make things right for you.

The red coloring of the "R" in the type number above is just to point out the difference. You don't need to make it red when communicating with someone about it, but make sure they understand that having the "R" is critically important.

Thanks Skip. Will do. The problem isn't connecting the cables with the terminals. The battery won't physically go into the enclosure. It hits the shields in the back of the battery area.

Could something have possibly come out of position in the battery compartment? All the Generac home standby generators that I've seen or read the specs about use the Group 26 size battery. The Group 26R that you need is the same physical size but just has the terminal positions reversed from the 26.

Check the battery you have carefully and see if it is a Group 26 or not. The physical dimensions of a Group 26 or 26R battery should be 8-3/16" (L) x 6-13/16" (W) x 7-3/4" (H).

With our battery in a 5875 (a different brand battery) I need to push the top of the battery in first, and the rest follows. When removing the battery, I lift it up and pull the bottom of the battery free first. It is a tight fit. There is a carrying strap on our battery that makes lifting and positioning it a bit easier (but not easy.)

On the 20's you need to loosen the plastic shroud ( 2 metric bolts ) un-hook it from the lower catch,jiggle it up out of the way and install the battery. Then put it back together. poof! done.

wow, not many user serviceable parts in the gensets, yet it sounds like they've made it overly difficult to just service the battery.

The 8kW through 20kW use the same enclosure. As they get bigger the saying regarding 10 lbs in a 5 lb bag comes to mind. Things just get a little tighter. But actually removing the shroud is not bad.

I have installed GE, Briggs and Kohler and I personally prefer the current air cooled offering by Generac. The top opens easily, the front comes off easily, propane conversion is easy, valve access is easy, oil filter access is right in front.
The Nexus controller is nice and customers like the way they look.

Thanks!

Thanks! I have big hands so the wiring has been fun so far, why not have more fun with what I thought would take 2 minutes like the battery! Thanks for the info.

Battery Update

The tip about removing the shield worked. I was able to get the battery inside and reattach the shield for the most part. There are clips on the far side of it at the top and bottom. I was able to get the top clip to snap back in but not the bottom. With the two bolts holding it, shouldn't go anywhere. Thanks again for all the help.

Haha...that sounds like a Tech. that I work with. Excellent Tech., but because of his monster grippers, he's better suited to working on a 20 cylinder Detroit Diesel as opposed to the residential systems. If you want to see some funny stuff, ask him to wire a phone or CAT5 jack :)

Its true that they try to pack ll that crap in a small enclosure. The battery fitment on post 2008 generator has always been tight regardless of the battery being a group 26 or 26R. The 26R is used so the positive post and terminal of the battery is not right on top of the generators sheet metal.

I just break off the extra plastic extrusions from around the bottom of the battery and it slips right in.
