Currently plugged into shore power and charging batteries at 1200W. Solar this morning was 50ish watts in our shady spot in Yellowstone, ramped up to 515 watts or so once the day got a bit later and we were outside the park. Just not even sure where to begin troubleshooting because readouts have been looking normal despite the weird events. I've attached some photos as well - apologies in advance for the kabalsalat! I've tried cleaning up a bit, but definitely have room for further improvement. Air temp was chilly last night but not "that" chilly considering the batteries are inside, outside was in the 45-50F range while we were probably 55-60F inside.Īs we speak, we're in an RV park outside Yellowstone connected to shore power to get a full charge all over again, but more importantly for cell service to connect to you guys and try to troubleshoot something. The BMV eventually turned itself back on with a voltage of 13.05V, so not "actually" a low voltage or even 0% SOC. Once solar started kicking in around 8:30 am, we started getting some intermittent functionality of 12V users as one would expect. First thing this morning, we packed up and left Yellowstone to run some errands including buying a multimeter as well as dump/fill the Airstream. Silly me, left the multimeter at home so I didn't have a way to manually read the voltage. Inverter was completely off despite being in "ON" position. Checked the screen of the device itself and it was shut off. Around 1:30 am my wife woke me saying it was too quiet, she couldn't hear the fridge running. Batteries are inside, under the main bed.įast forward another 30ish hours, we went to bed and night temperatures drop fairly rapidly. No apparent temperature issues, outside temp was 84F and inside the trailer was probably 78ish. The battery guard appeared to have done its' job, albeit at the cost of the battery guard as the only way I was able to restore power was to bypass it. This tripped the battery guard, took me a little bit to locate the failure, initially thought it was the transfer switch because I've had a few issues with that. The SmartSolar controller said that the battery voltage had dropped to 9.12V which is obviously well below anything a LiFePo4 battery should ever see. The Multiplus had a low battery alarm, the BMV showed 57% and something like 13.35V. After 2 days of being parked at Yellowstone in a relatively shady spot and arriving with full SOC of 14.59V on the Battle Borns, 'something' tripped in the system and shut me down. Recently I completed a solar setup that I 'thought' was working well, or maybe currently think so? I'm not sure. Historically we run 5-6 days on batteries alone (setup details below). We've been parked for a few days in Yellowstone National Park in the US. The system now allows the driver 4 minutes to start the vehicle before the battery disconnects again.Honestly, vague title because I'm unsure where to even begin. To reconnect the battery, the driver needs to press the momentary switch. When the battery is disconnected, a LED indicator on the dash mounted switch blinks to let the driver know that the system has disconnected the battery. This feature prevents a shutdown in the event of a charging system failure while driving. If the ignition switch is turned on, the system will not disconnect the battery under any circumstances. When the voltage drops below 12.1 / 24.1 volts for approximately 4 minutes and the ignition is off, Battery Guard 2000 will automatically disconnect the battery from the vehicle’s electrical system. This may happen if a light or an other accessory is left on for long periods of time.īattery Guard 2000 constantly monitors the voltage level on the battery to determine the level of charge. NO MORE FLAT BATTERIES WITH BATTERY GUARD 2000!īattery Guard system is intended to be used in vehicles to prevent the battery from inadvertently being discharged by some unwanted load.
