BankManager™

NOTE:  Our default current sensor  is sized for 200A of charging or discharging.  This is approprate for 90% of our customers.  If your system moves more then 200A, other current sensors are available.  As the current sensor gets larger, its percision decreases, but even the 600A sensor would work in any system (You just might see the 10ths-of -amps display jump past some digits.)

If don't use the 200A sensor, you need to tell your BankManager™ what you have installed. You can do this via the menu when you set up your system.

NEW! BankManager™ Generation 2

This unit works for 12V, 24V, 36V, or 48V systems, and can be used for marine, RV, off-grid homes, and other hybrid battery applications. This unit includes a sensor and is compatible with the Universal and Generation 2 spare/replacement parts listed below.

Note: Installation requires an appropriate contactor, sold separately. (See below.) 

$380.00 USD

BankManager™ Bistable Contactor BEST CHOICE 

A contactor is required to install your BankManager. We offer a high-quality, 300A, continuous-duty bistable contactor specifically made for BankManager™ units.  This device is well manufactured in the United States by a company in North Carolina. We recommend all users add this item to their order. 

If your installation will need to pass more then 300A continuously, you can use two of these contactors in parallel.

If you prefer to supply your own contactor, please contact us about compatibility. Most any normally-open, normally-closed, or bistable contactor with low-side signaling will work, though our installation manual is written to accommodate our custom contactors. 

(Note: 48V/36V versions now available!)

$180.00 USD 

BankManager™ Monostable Contactor  BUDGET-FRIENDLY 

This is a budget-friendly alternative to the bistable contactor. This device should ONLY be used with 12V or 24v systems, and requires you to set our BankManager™ to monostable mode through its menu during setup. See the manual for full details. 

Please note: This contactor is rated by the Chinese manufacturer for 200A. Note that this is a monostable relay—so it constantly uses a nominal amount of power to remain in the “on” state. (It’s not a lot of power, as it has an economizer circuit—just milliamps—but it adds up. So if you want to minimize waste, we recommend the bistable contactor above instead). 

If you prefer to supply your own contactor, please contact us about compatibility. Most any normally-open, normally-closed, or bistable contactor with low-side signaling will work, though our installation manual is written to accommodate our custom contactors.

BankManager Generation 2 Circuit Board (Spare/Replacement)

The latest-available version of the BankManager™ software, on a board sized to fit inside the Generation 2 case.  

This board is compatible with Generation 2 BankManager™ only.

$250.00 USD

BankManager™ Universal Current Sensor (Spare/Replacement)

Please choose your charging amperage. 200A is adequate for 90% of applications.  If your system moves more then 200A, other current sensors are available.  As the current sensor gets larger, its percision decreases, but even the 600A sensor would work in any system. (You just might see the 10ths-of-amps display jump past some digits.)

If don't use the 200A sensor, you need to tell your BankManager™ what you have installed. You can do this through the menu during setup.

If you think you need a sensor with higher amperage, please contact us before ordering. 

$65.00 USD

This sensor works with all generations of the BankManager™.

"CRUISING PACK" SAVINGS

If you’re going off the beaten path, and you’re the kind of sailor that likes to carry spares, these might be the packages for you.  They contain backups for the core BankManager.  You will still need a contactor and spare if you wish.

(Protip: If you’re ever hit by lightning or a voltage spike, you’ll be happy if you’ve wrapped your spares in a plastic wrap, inside aluminum foil, and stored them in a safe, dry place.)
