This meter is an important addition to modern battery management systems. Monitors voltage on up to 3 battery banks, Amps for charge and discharge and capacity remaining in amp hours /percentage utilising peukerts exponent (house bank only) with the added function of a bilge monitor allowing 24 hour monitoring of your bilge pump.
#BEP BATTERY MONITOR FULL#
The Contour Digital Monitor offers a comprehensive range of functions to allow full monitoring of your batteries and charging systems. That is why the 13 year old Smartgauge that doesn't use a shunt has been so successful.BEP Panel Mounted DC Systems Monitor Product Description Moving the starter battery common negative to the other side of the shunt always confuses people because they think the shunt will then also be monitoring the charge current going into the starter battery!!!!Ī very well respected marine engineer in Maine, USA, found that “perhaps 7 out of 10 battery monitors he sees installed by both pro's and DIY's are wired incorrectly (shunt wiring) and 9.5 out of 10 are programmed incorrectly.” This will bypass the shunt and not show any current into the service battery when the service battery is charging. This will be via the service battery negative stud and then, via common earth, to the starter battery negative stud, which is usually wired to the engine block and hence to the negative of the alternator. Now try and follow the return path of the electrons to the alternator from the service battery. This supplies positive volts to the starter bank and the service bank. This will happen when split charging VSRs or diodes join the banks together. This error is probably one of the major causes of battery monitors not reading the alternator charging amps going through the service battery. So the starter battery common negative - that connects the starter negative to the house bank negatives - must also be connected to the bus bar. With a battery monitor installed that has the shunt in the negative cable the bus bar becomes the new negative post for the service bank. If not all of the devices drawing current or charging the service bank are going through the shunt then the Ah count will be wrong. With multiple batteries in parallel, and not all in the same location, it is often difficult to know what wires are going where. This is in itself confusing as a stand alone house bank will always have a cable on each negative and positive stud to tie several batteries into one big capacity bank. The instructions are usually that all battery negative cables MUST go via this bus bar. The shunt must be as close to the battery as possibly – for most brands on the negative post – and a new bus bar must be installed immediately after the shunt to take all the negative cables, and any new one that might be fitted later.
#BEP BATTERY MONITOR MANUALS#
The installation manuals are usually not very clear, especially the BEP. Make sure you tell an electrician fitting new kit that you have a Battery Monitor installed. Often extra equipment is added at a later date and the installer may well follow the installations instruction. I'm sure you followed the MPPT instructions to the letter and installed the new equipment “directly to the battery”, but not via the shunt bus bar. Shorepower on, solar on, house battery on = 14.5v, (2.9 amps on Victron MPPT), -0.7 amps discharge at the BEP battery monitor No shorepower, solar on, house battery on = 14.3v, (3.1 amps charge on Victron MPPT app), -0.7 amps discharge at the BEP battery monitor No shorepower, no solar, house battery off = 13.7v, -0.5 amps discharge (there are some always on circuits) Some values (all taken on a sunny day within a few minutes)
The discharge values seem to correspond with what I would expect the charge to be. Indeed, whilst motoring under autopilot and with the instruments and fridge on the BEP was showing -11 amps discharge. Even on shorepower it is indicating discharge whilst the charger is showing "float".
#BEP BATTERY MONITOR BLUETOOTH#
The MPPT has Bluetooth and is indicating I'm typically getting 3amp charge when sunny.but the battery monitor is indicating "-0.X discharge".
#BEP BATTERY MONITOR INSTALL#
Again, fairly simple to install (I may regret saying that after you lot have pitched in correcting me ! I've not had chance to really see it in action before then installing an 110 w solar panel controlled by a Victron MPPT. Have installed a BEP DCM Battery monitor (the shunt connected by pro's as they are heavy duty cables and I wired the "sense" wires to the monitor - its was fairly straightforward).
