[RE-wrenches] Battery Bank Off-gassing CO?

I was emailed recently by someone in my area saying that she thinks here battery bank is going bad and poisoning her home.. My firm did not install her off grid system. Her original installer will not respond. She has an 6yr old battery bank w/ 6 Trojan L16H's (48V). The system has 1.2kw of

Here in a region with a huge percentage of homes having natural gas furnace heaters [with resistance backup,] carbon monoxide fumes are a very real concern. If her house has a NG or oil burning furnace I'd look there for a stuck or mal-adjusted pilot light. If her house is sealed tight, and I'll

Hi, Daniel~ If your client has quantity six of the L16H batteries, that's only a 36 volt string, not 48 volts. Let's hope this is only a typo. The only vapor emissions likely from a group of floodies are oxygen hydrogen...then there's dilute sulfuric acid mist...but no carbon component. Ask

Hello Daniel, Unfortunately, I've had to deal with this issue in the past and after countless hours of effort (end-users, fire departments, and my own), the conclusion and/or corrective action has always been to replace the CO detector. Carbon monoxide or other carbon oxides are not expected

By the way, it was a typo, it is an 8 battery system @48Vdc. We just put in an order for a power vent, the home owner is going to install this herself, as she is handy enough and has done PVC plumbing work before. I will let the list know if this solves the issue or not. Also I plan to have

I agree w/Don's comments and would add that I'm migrating away from Grundfos to Lorentz. My main reasons are the poor CS from Grundfos, the inability to rebuild the pump in the field and the electronics down the hole. In addition Lorentz has a huge line of DC pumps up to 45gpm and soon beyond

[RE-wrenches] Interstate UL-16 HC problem

I have 2 systems that I am trying to correct that another local dealer has installed. This one is 2 strings of (8) UL-16 HC Interstate Batteries, 16 batteries total. We cannot get the batteries to charge over 1.225 despite discharging them and generator charging them till everything shut down.

IMHO Interstate makes a decent battery. It sounds like to me that you are not Equalizing but just trying to BULK. You'll need at least one robust EQ cycle to bring the SG's in line and likely 2-3 a couple of days apart. At least the Magnum's of a couple of years ago are not intuitive to get

Hi, I'm Looking for products or techniques that have been used as a raceway for wire protection on the back of a ground mount array. The local AHJ is not accepting a fence. We are required to cover or shield our USE module wiring below 8'. Side question: if we directly attach (self tappers) a

Bob, Sulfation, I'd say. Try EDTA. Trailhead Supply. See Home Power marketplace ad for contact info. If it's not sulfation then maybe it's simply diluted electrolyte(accidental, or intentional) which would make the batteries have lower performance AH wise but should last a long time (plates

That is a tough one to diagnose, but I think you have some sulfation, I have used interstates and had reasonable luck.  They act more like a traction battery than a RE battery.  This might be a job for a desulfator or a very long slow charge.  It takes a long time to get sulfur to leave the

IF those L 16s are much over 5 years old, they could be gone. L16s (of any brand) have less cycle life than a golf cart battery, just check the charts. They also don't fair very well long term in float charge. You can probably EQ them back to life as already mentioned, but then after 6 months to

Nick; I'm not basing this information on my own anecdotal experience, its based on cycle life data from Trojan. This test data is done independently by the BCI (Battery Council International) The T105 gets 750 cycles to 80% DOD, while the L16 only gets 600 cycles to 80%DOD. Obviously, your
