However you can control the BP in two other ways.

With the link open no current will pass from the IN to the OUT. When you remove the link there are three ways to control the BP. Any additional information would be much appreciated. This seems to conflict with the answer above and I have been unable (or unwilling due to the conflict) to get this working. In this case solar is the IN and the battery connection is the OUT The BatteryProtect is a one way device has an IN and an OUT terminal for power. Take the output of the NC terminal to the Remote connection of a BatteryProtect and then program it for PROGRAM C (lithium) The BatteryProtect will be ON when its remote terminal is +12 volts which will be when there is no alarm. The conditions of the NO and NC terminals reverses when the alarm condition is met. Supply 12 volts to the COM terminal and the NO (normally open) and NC (normally closed) terminals will be ON (normally closed) and OFF (normally open). The BMV has a relay terminal at the back and you program it to be on or off depending on temperature conditions. Yes you can do this easily with a BatteryProtect. Can I use the relay on the BMV-712 display monitor to directly manage a Victron BP220 to cut-off charging from the solar panels? I am currently using a Victron BMV-712 to accurately monitor the battery temperature. I'm looking for a solution that will disable solar-only charging to a 24 volt lithium ion battery at low temperature. I ask because victron support suggested that I talk to a major distributor in the US about a similar question and I got a different answer. Is there any more feedback on this question. Is there not a single device that dioes all of this? It does seam like it gets quite complicated and expensive for a system which to me would be a very common scenario. It would also be good to possibly expand to be able to also charge off the cars altenator and also be protected from there. Would it be possible and easy to wire it so that the battery can be discionnected from the output (loads) when depleted, yet still be able to be charged up from the MPPT and still have input(MMPT)/output power(when open) monitoring from the BMV? If using the victron MMPT can this not just protect the battery/s from over charge via settings to shut off once voltage reached? Can it talk to the BMV and turn off based on SOC% too?

If not, like above then I assume the SBP is needed? will it work for both low and high V/SOC% cuttoff? I have read that it wont work on high amp loads so not usefull as a disconnect for under/low charge. I am looking for a simple but expandable system to work with solar and a lithium battery or two and it has been unclear so far on:Ĭan the BMV 712/202 included relay/monotor unit protect the battery/s via high point and low point disconnect (overcharge/undercharge).

I'm pretty new to this stuff and feel a bit out of my depth.I am also quite confused as to how to wire, program a similar system to you and what products are required. I'm thinking that since my settings on the BMV have the charged voltage at 13.2V, when the solar gets up to the 14.7V for absorption it is setting SOC to 100%. I looked into my solar and converter specs and with the solar, the absorption voltage is 14.7V and the float is 13.6V. But when I switch to solar, the SOC often jumps right up to 100%. I left the settings on the BMV at the default and it seems to work well when I'm just charging off the converter.

The other half I'm using a portable Renogy 100W solar panel with their Voyager charge controller. About half the time I'm charging them from my RV converter (usually via a generator), which is a Progressive Dynamics PD4045KA. I have 2 group 24 flooded lead acid batteries, that add up to 124 Ah. Hello, I could really use some help figuring out the settings I need to use on my BMV-712 for my RV setup.
