Remember when I said easy? This is it. You run a duplex 14GA wire to the house bank cross-connecting it as shown, with the neg on one end of the bank and and the fused positive on the other end of the bank. For the start battery voltage a single 14GA wire goes to the B2 terminal.
IMPORTANT: Do not wire the Smart Gauge to any place other than the actual physical battery terminals! This is very important for accuracy. In order for the Smart Gauge to work properly the positive & negative leads from the Smart Gauge need to attach directly to the physical battery terminals, not a positive or negative bus, a shunt or anywhere other than the actual battery terminals.
The SmartGauge's negative and positive wires and the battery banks system take off positive and negative points must be wired as shown in this diagram. The SmartGauge and system wiring must not simply pull from an end battery of a parallel bank. Negatives off one end and positives off the other end.
WARNING: The Balmar Manual is INCORRECT (requested corrections on multiple occasions) on how it shows the SmartGauge to be connected. Please use this connection method if you want the best accuracy.
The Smart Gauge self consumption is less than 5mA when the display is asleep and just 15mA when the display is lit.
5mA = 0.005A
15mA = 0.015A
In 24 hours it consumes only 0.12Ah. In an entire week it consumes just .84Ah. It should be noted that a traditional battery monitor using a 500A/50mV shunt does not have the resolution to even track this consumption. Because the SGBMU tracks voltage it CAN actually track its own self consumption! The self consumption of the SGBMU can actually be less than a FLA batteries own self discharge in hot weather.
EGREGIOUS WEB SITE PLUG:
Please remember this FREE web site is 100% supported by you my readers. I do not have annoying advertising or charge a membership fee! I try to keep this site free but it is becoming harder and harder to do.
Donations simply were not cutting it so I have had to add some products to the site to help support it. You can buy the Smart Gauge on this site. I may not be the absolute least expensive but I do not have the buying power of the big guys. Remember where you read and learned about this product if you choose to buy one.
