If your cottage or cabin depends on batteries for electrical power, here’s why battery system monitors should be a part of your electrical system.

CONSERVATION

Helps save valuable Energy by letting you see how much you’re using.

• Use “amps” to educate users about how much energy different electrical loads draw
• Check that all loads are really off when you think they’re off
• Check for “phantom loads” – small loads that steal power 24 hours per day
• Keep informed about how much energy you have left in your battery system
• Reduce generator use by knowing when you can efficiently shut it off because batteries are approaching full charge

BATTERY CARE

Provides information you need to protect your battery investment.

• Know when to turn on your generator to avoid damage from over discharge
• Check that charging systems are charging to correct voltage for longest life
• Be reminded not to let batteries go too many days between a full charge

SYSTEM MAINTENANCE

Helps locate system problems when they occur.

• Monitor solar arrays and inverter/chargers to be sure they are still charging at proper rates and voltage
• Find out if batteries are still holding energy properly
• Even if you’re not an expert, a dealer or other knowledge-able person can more easily help you “by phone” to locate a problem if you have a monitor on your system

BMK from Magnum Energy

Monitoring your battery bank is easy with the Battery Monitor Kit (ME-BMK) from Magnum Energy. Acting as a “fuel gauge” for your batteries, the ME-BMK monitors their state of charge (SOC) and then provides this information in an easy-to-understand display via the ME-RC remote. With accurate SOC readings, you can avoid unnecessary battery recharging, saving on fuel and long-term maintenance costs.

Available readings from the ME-BMK:

• State of Charge (SOC) 0 – 100%
• DC volts
• DC amps
• Amp hours in/out
• Resettable amp hours out
• Total amp hours out
• Minimum volts DC
• Maximum volts DC
• Temperature compensated
• Auto detects input voltage

Bluetooth inside

With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era.

Use a smartphone or other Bluetooth enabled device to:

• customize settings
• monitor all important data on single screen Inverter and chargers
• view historical data
• update the software

Other features:

• Battery voltage, current, power, amp hours consumed & state of charge
• Remaining time at the current rate of discharge
• Programmable visual and audible alarm
• Programmable relay, to turn off non critical loads or to run a generator when needed
• 500 Amp quick connect shunt and connection kit
• Shunt selection capability up to 10.000 Amps
• VE.Direct communication port
• Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health

• Wide input voltage range: 6,5 – 70V
• High current measurement resolution: 10 mA (0,01A)
• Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings

The TriMetric

Features:

• For 12V to 48V battery systems
• The “amps” or “watts” display measures the rate of energy going in or out of your batteries
• The “% Full” display is the most accurate way to keep track of how charged or discharged your batteries are until the battery voltage gets really low
• The “volts” display can warn you that you are near discharge and it also lets you discover if your charger is charging to an optimum voltage which is important for maximizing your battery life.
• The “days since charged” display shows how recently the main battery (system) was fully charged, so if it hasn’t been charged recently you can perform extra charging if necessary to help maintain the capacity of your batteries.
• An audible alarm can signal a low battery
• Data logging to diagnose system problems
• Plus 5 other data functions

FnDC from OutBack Power

OutBack Power’s FLEXnet DC is the ultimate DC system monitoring device. The integrated networked communications make valuable, usable data available from your system and viewable on an OutBack MATE communications device, providing you with the critical answers about your system’s health, performance and efficiency.

Features:

• Simple DC system monitoring
• Extends battery system life
• Reduces generator runtime and fuel consumption
• Provides 128 days of system data logging

When used with an OutBack MATE you can view:

• Battery Status Screen – Easily see your systems current condition, SOC
• Now Summary Screen – Monitor the amount of power your system is currently producing and consuming as well as the amount of power going IN and OUT of your battery bank
• Today Summary Screen – Monitor the cumulative energy your system has produces and consumed as well as the total amount of energy that has gone to charging your batteries today
• History Summary Screen – Review energy production/consumption for the previous 128 days
