Testimonials

I don’t see anymore how it is possible to manage a solar system without the full monitoring and control provided by Wattmon, it is a small investment that makes the big one - of the solar system - finally 100% worth its value.
Didier / Auroville / India
I am very happy to be using a Wattmon; it is very practical and controls the charging, from the mains, of my battery bank during the night time, whenever the battery charge level falls below a certain level and stops the charging when it reaches another level. All these parameters are programmable and can even be managed remotely. As a result I believe my battery will have a longer and better life than otherwise. The Wattmon is being continuously improved and upgraded...it's a very necessary accessory to your solar power system.
Angad / Auroville / India
We have been impressed by the flexibility of the Wattmon, its simple programmability enabled us to use it for a complicated application that would otherwise have required designing our own device.

The Solar Radiation Sensor, or solar pyranometer, measures global radiation, the sum
at the point of measurement of both the direct and diffuse components of solar
irradiance. The sensor’s transducer, which converts incident radiation to electrical
current, is a silicon photodiode with wide spectral response. From the sensor’s output
voltage, the console calculates and displays solar irradiance. It also integrates the
irradiance values and displays total incident energy over a set period of time.
The outer shell shields the sensor body from thermal radiation and provides an airflow
path for convection cooling of the body, minimizing heating of the sensor interior. It
includes a cutoff ring for cosine response, a level indicator, and fins to aid in aligning the
sensor with the sun’s rays. The space between the shield and the body also provides a
runoff path for water, greatly reducing the possibility of rain- or irrigation-water
entrapment. The diffuser is welded to the body for a weather-tight seal; it provides an
excellent cosine response. The transducer is an hermetically-sealed silicon photodiode
with integrated amplifier . Spring-loaded mounting screws, in conjunction with the level
indicator, enable rapid and accurate leveling of the sensor. Each sensor is calibrated
against a secondary standard Pyranometer in natural daylight.

Zero Feed and DG Protection

Zero Feed - The Why

In India many states experience frequent and crippling power cuts.  Solar rooftop systems are springing up everywhere, from small residential houses to large factories in attempt to save costs and in so doing reduce carbon emissions.  Many states have not modified their policies yet to allow feed in, which in turn means that all solar generation needs to be used within the premises.   This is fine when the installed capacity is much less than the average load, but when a larger solar plant is installed problems can and will occur when loads are less in peak solar hours and during weekends.

Zero Feed - The How

A power meter is installed at the incomer of the building, and is used as a reference to determine the active power load on the building.  This meter needs to be able to communicate with Modbus RTU.  The Wattmon device is connected to both the power meter and the inverters.  It will regularly poll the power meter to determine the active power.  As it reaches a threshold value that can be set by the user, it will ramp down the output power on the inverters using power control commands on Modbus RTU.  This will effectively limit the amount of generation dynamically so that exporting of power does not happen.

DG Protection - The Why

Diesel generators bridge the gap during power cuts and in some locations they are used 24/7.  When coupled with solar grid tie inverters, a saving of fuel can be achieved.  However, it is important to balance the amount of solar power generated so as not to trip the genset, which effectively means you need to maintain a certain minimum load on the generator at all times.

DG Protection - The How

A power meter is installed on the output of the genset, and connected to the Wattmon in the same way as with zero feed.  The Wattmon monitors the energy generated and if it drops below a set point, it will reduce the power of the inverters so as to ensure that the generator does not trip.  

Both these systems can be installed at the same site by using two power meters and some software customization which will allow the set points to vary based on whether grid energy is available or whether the system is running on the generator.
