I have an Orion-Tr Smart 12/12-18 Isolated charger installed in my travel trailer, but it only charges my battery @ 5-6 amps, and the app actually shows 'charge is disabled', would appreciate it if someone could help figure out what's wrong, some additional information:
- Charger is connected through my SUV's 7pin cable, the 12v charging wire in 7pin cable has a 20A fuse in SUV's fusebox.
- Although it's isolated charger, I had to connect both input ground and output ground wire to my trailer's ground busbar, as I need a common ground for other wires (brake, turn signals) in the 7pin cable.
- I also wired the running light wire of 7pin to charger's switch pin, and verified when I turn off the running light from SUV, not charging was happening and when I turn it on, charge resumes at 5amp.
- I was charging 200ah 40% SOC LiFePo4 batteries, which should be able to take way more amps than 5amp.
- SUV's alternator is rated 180A.
- The app actually displayed 'charge is disabled'
Anything wrong? I also noticed when I changes the settings from config, it actually trip the fuse twice, indicates somehow there was > 20a current flow through fuse/wire,
