1. Introduction
This instrument is a panel mounted 96 x 96mm DIN Quadratic Digital metering system for controlling
upto 20 Solar Inverters of PVSA make. The instrument is available in two models* : With
Generator Sense and Without Generator Sense. The instrument prevents the excess solar power
generated by inverters from getting fed back to the grid / generator. The instrument does this by
measuring the important electrical parameters like AC voltage, AC Current, Frequency, Active Power,
Active Energy at the grid / generator and monitoring the power from solar inverter(s). The instrument
integrates accurate measurement (All Voltage & Current measurements are True RMS upto 31st
Harmonic) with 320x240 Pixels touch screen TFT LCD display.
This instrument can be configured and programmed at site for the following parameters of grid /
generator:
PT Primary, PT Secondary, CT Primary, CT Secondary (5A or1A).
The front panel has a 3.5” Touch Screen through which the user can navigate through the available
measurement readings of the Grid / Generator, Solar and Load and congure the product settings.
The main screen is divided into 4 submenus, namely GRID /
GENERATOR, LOAD, SOLAR & SETUP. Each submenu contains a
list of options. By touching the icons cum submenu access buttons
on main screen, submenus can be accessed. GRID / GENERATOR
submenu can be used to access the power, active energy : import &
export and additional grid / generator parameters namely THD, on
hour, number of Aux interruptions, voltage, current, etc. LOAD
submenu can be used for accessing the Power Contribution of Solar
and Grid / Generator to the Load. SOLAR submenu provides all the
information about the PV Plant in tabular and graphical form.
*Note : The Generator parameters and settings related to Generator referred to in this booklet
are available for the instrument with Generator Sense only.

2. Measurement Reading Screens
In normal operation the user is presented with one of the measurement reading screens out of several
screens. These screens from particular submenu may be scrolled through one at a time in incremental
order by touching the “ key” and in decremental order by touching “ key” on that screen.
