There is a cable from the chassis to the negative post on the lithium battery. Posted: Mon 3:33 pm Post subject: Re: Renogy 500 A Battery Monitor Problem Posted: Mon 2:10 pm Post subject: Re: Renogy 500 A Battery Monitor Problemĭo you have any other connection to the battery negative via the BMS negative than the sampler shunt, and is the van chassis connected to the other end of the shunt? ![]() Before installing the battery i charged it to 100% with a Victron charger. I have gone over the wiring and believe it to be correct. When driving (no load) the capacity indicator percentage of the battery dropped (from 100% to 98%) along with the discharge indicator of the battery (100 Ah to 98 Ah) which suggest that I am losing capacity while driving. When I start the van the voltage increases but the present current (amps) is a negative. When I add a load (engine off) the voltage drops but the present current (amps) do not change. Everything is installed but the readings on the monitor do not seem to be correct. With that I added a Renogy DCC 30S 12 V on board battery charger, Renogy 500 A Monitor, Renogy 100w Solar Panel and the B-2 Bluetooth Module. I just installed a 50 amp GoWesty lithium battery.

Today the solar controller with one solar panel attached recharged the battery to 100% SOC (boost voltage 14.4v), then went to 13.8v float charge, resulting in 0 amps going into battery (its already at 100% SOC) and all other small dc loads were supplied by the solar controller at 13.8v. ![]() The inverter introduces another 2-2.5A parasitic load on the 12v system if left on when not in use. So if I turn the inverter off when not in use at night, the 12v system only loose about 12 amp hours a night parked. There is about a 1 amp parasitic load on the 12v dc system in the camper, heater/ac thermostat, three way fridge eyebrow controller, smoke detector, propane detector. The BT-2 connected the DCC50S with the iPhone, no problems. I do believe that some of the settings are not required for a battery charger/solar controller with no LOAD hookup.Īnother day with sunshine. I do have some reasons for some of the settings. You might want to choose other set points. I have three 12v 100AH LiFePO2 batteries in parallel, the DCC50S, and a charger/inverter MSH1230 M.Each of the three batteries have their own BMS internal to the battery case. No surprise here as the DCC50S manual is also very poorly written and the devices connected to the DCC50S are not consistently named in the manual.ĭoes anyone want to take a shot at defining any of these settings described above ? Their min/max values and interaction with other settings are not defined in the owners manual. These settings are not defined anywhere in the owners manual. (many of the setting descriptions are truncated) If you select Battery Type 'USER', the battery type indicator light turns white. There are several settings you can change in the Renogy BT app. I do not know why it would not connect right up earlier. I got it to connect to the phone with Bluetooth so there is hope. Viewed record and other screens, then came back too settings screen to find that most of the settings I saved were still there (found that the EQ min time had changed from 0 to 10). I was able to read data from the DCC50S, view the device battery 'USER' type settings with the Read button, update a few settings, use the Save button to save the setting changes. It connected to the BT-2 Bluetooth device. Then reversed the process, turned on service battery + circuit switch, turned on the solar panel + circuit switch and plugged in the BT-2 cable to the DCC50S RJ45 port. Then I tried unplugging the BT-2 cable from the DCC50S RJ45 port, turned off the solar panel input (even though it was dark outside), Opened the 12v dc + switch to the DCC50S service battery + port. After trying everything I could think of, with no Bluetooth connected state on Renogy-BT app, I was about to give up. ![]()
