When the CCGX is connected to the inverter (by an ethernet cable), the inverter waits for a signal from the CCGX before it will turn on.
The actual reason my inverter would not turn on in post #1 is because of no power to the Color Monitor (CCGX). for ~$25 at the local auto parts store.įor those not familiar with my setup, here's a schematic (should have posted this before now!) A better alternative (IMHO) is to buy a Battery Tender Jr. While this may work, not sure it's the most efficient since I'd have to run my 6.7L diesel at idle for quite a while to get the batteries charged to the point where the inverter will come on.
(The trailer is now configured as if the original OEM configuration disconnect is OFF, thus minimal load on the batteries). (Remember-I have an extra one that allows me to do this.) The Battle Borns would have turned back on when they sensed no load.Ģ) Turn on the truck with the 7-pin connected, thus supplying a trickle charge of 12V.ģ) Turn on the first disconnect. Potentially it might work if I'd done it in this order:ġ) Turn off the disconnects, completely isolating the batteries. 9 Aug-and there was no power to the CCGX! See post 14 for more info. Guys - would being hooked up to the truck through the 7 pin connection with engine running slowly charge the batteries and at an acceptable rate ? If so, I wonder how long it would take to get the RV back in business.ĭanWith my truck that didn't work-at least the way I tried it the first time (both disconnects where on, thus the Battle Borns stayed off). (Duh, huh?) I might need to toss a Battery Tender Jr in my emergency kit, too, should I get myself in this situation again. Lesson learned: if leaving the trailer disconnected for any length of time, turn off the inverter and components that will drain the batteries. I'll know soon if I screwed something up. After about 45 minutes I flipped the shutoffs back on and switched the inverter to "Charger" mode and everything powered up including BULK mode recharging of the Battle Borns. I hooked up the charger directly to the batteries (prior to the shut-offs). I have a Battery Tender Junior (750ma) for my lawn tractor so I gave that a shot. I called AMSolar and they recommended hooking up a small (<2 amp) charger to get the batteries above 11v with the shutoffs enabled so the inverter "sees" the batteries. For those that followed my thread on a different forum, removing all four batteries would involve a LOT of work.ĩ Aug edit: The following paragraph has incorrect information-see post 14. I called Battle Born and they recommended removing all four batteries and then individually "jump starting" each battery. So I was caught in a catch-22: the batteries needed charging but the inverter/charger won't power on because the batteries need charging. When I turned the shut-offs back ON the batteries shut down again (down to 1.4vDC). The inverter is on the output side of the second disconnect switch (which were now both turned to OFF) so there wasn't a simple way for the inverter to "see" the 10.97v. The Victron I have will not power on if it doesn't "see" a battery. (The Battle Born's built-in management system, or "BMS", shuts down the battery so it isn't damaged.) The battery's built-in management system is why this happened. I turned off both of my disconnects (completely isolating the batteries from the trailer) and the voltage at the batteries jumped to 10.97v. I tried connecting with the truck running-nothing. Note that I verified 110vAC was at the inverter. (Yikes!) I hooked up shore power but my Victron inverter/charger would NOT turn on. Measuring directly across my four Battle Born batteries showed 1.4v. What I found today was a dead trailer-no 12v anywhere. I'll spare you the long story how I got here if you'll accept I did something dumb.
