Tech Tip - Amp Hour Meters With the use of an Amp-Hour meter, you can tell the condition of your batteries at a glance. An amp-hour meter is the best indicator of your system’s condition. As you use power, the meter counts how many amp hours are used. As the battery is charged, the meter goes backwards, toward zero. When the battery is full, the meter reads zero. This type of meter is a must for nickel-cadmium and nickel-iron batteries, where it is hard to tell state of charge from voltage, or specific gravity. The main destroyer of lead acid batteries is sulfation caused by undercharging. These sophisticated meters help you keep track of your battery’s state of charge so you can keep ’em charged. Get maximum life out of your batteries and save money and system down time. Note: Amp hour meters lose accuracy if batteries are always run in a very discharged state. |

This amp-hour meter for 12 or 24 (and 48 with adapter) volt battery systems reads volts, amps and amp-hours on an LED display. Amp-hours can be displayed in actual amp-hour numbers, or as "% full". An LED lights when the battery is charging and flashes when the battery has been fully charged. Another LED flashes when batteries should be recharged, equalized, and during low battery voltage. It also records minimum and maximum voltage, days since batteries were last charged, days since equalized, and total lifetime amp-hours withdrawn from the batteries.
The Trimetric can be located hundreds of feet away from batteries using inexpensive 4 conductor twisted pair meter wire. For 48 V systems or additional lightning protection on 12/24 V systems, use a 48 V adapter with the meter. A shunt is required for operation. Use the 500 Amp shunt if you have a 12 V inverter larger than 800 watts or a 24 V inverter larger than 1600 watts. Use the 1000 Amp 100mV shunt for systems with stacked SW inverters or where continuous current is over 300 amps. The 1000A/100mV shunt has the same resistance as the 500A/50mV shunt and may be used interchangably.
Order shunt separately. Allows for a maximum battery bank size of 2500 amp hours. The positive lead to the Trimetric should be fused with a 1 amp fuse. Flush mount or use Wiremold box to mount.
Made in USA.
Dimensions: 4.5" x 4.75".
2 year warranty.

The new PentaMetric battery monitor system offers a lot more capability than the TriMetric monitor. The complete system consists of 3 parts: Input unit (near batteries), Display unit (shown above) and computer interface unit. It can monitor up to 3 shunts: For example; measure total solar input and wind input independently in addition to monitoring battery "state of charge". You can access the data with display unit (shown above) with LCD display and buttons up to 1000 feet from batteries.
An optional computer interface with (Windows) software allows you to control and read out all data from the computer. It has a relay output to control a generator or external alarm and it has audible and visual alarms for high and low battery conditions. 2 year warranty.

Why Use Monitoring Tools? Residential and commercial system owners and installers can now benefit from remote monitoring services for renewable energy systems. These services provide knowledge and control over energy system generation and demand and are remotely accessible via the internet. Monitoring systems typically consist of a local device that connects to the energy system, collects data, and communicates with the monitoring service provider’s central data center. Using such a service, residential and commercial system owners can remotely monitor their solar electric installations and see the impact of changes in consumption as well as problems such as tree shading or equipment degradation over time. Installers can check system performance, diagnose problems, and take corrective actions quickly and cost-effectively – often without ever leaving their office. Over time your solar energy generation and demand fluctuates. Periodic meter readings provide only a summary view of energy consumption, while telling you little or nothing about PV generation or about short-term performance issues. Good monitoring and display tools can help reveal trends, transient issues, cost-saving opportunities and emerging issues. They feature real-time and historical system performance graphs and downloadable data. Additionally, they provide the independent third-party, revenue-grade monitoring and reporting required to collect performance-based financial incentives. |

or wind system to provide visually engaging, web-based displays. This remote
monitoring solution allows you to manage and view
your solar energy system or whole-building energy usage in a single view. You
can view your system anytime, anywhere using a web
browser or mobile phone. Residential and commercial installers can assure
customers that their renewable energy system is operating
properly. Fat Spaniel provides views for post-installation support, alerting you
to failure issues and providing tools for remote troubleshooting.
The Fat Spaniel service also generates the regular reports required for
performance-based financial incentives available
under programs such as California’s CSI.
Residential Monitoring Service
Fat Spaniel’s Residential Monitoring Service gives
the residential system owner the monitoring and
visualization tools to understand their solar energy
system. The Residential Solution allows you to
improve your net-metering results and reduce your
electricity bill by managing your energy use.
