6.1.1. Testing of PV systems with single-MPPT inverter - single-phase AC output
The SOLAR I-Vw or SOLAR I-Ve meter (master) can perform check tests of efficiencies on
single phase PV installations by using the irradiance and temperature probes which are
connected to the remote unit SOLAR-02. This remote unit communicates with the master
unit (for the synchronization and download data operations) through a wireless radio-
frequency (
RF
) which is active with a maximum distance of about
1m
between units.
CAUTION
The maximum voltage between C1, and C2 inputs is 1000VDC (for SOLAR
I-Vw) or 1500VDC (for SOLAR I-Ve) and between P1 and P2 inputs is 265V
AC rms. Do not measure voltages exceeding the limits prescribed by this
manual. Should you exceed the voltage limits you could damage the
instrument and/or its components or endanger your safety
In order to guarantee the operator’s safety, while making the connections,
disable the system being measured by means of the switches/breakers
upstream and downstream of the DC/AC converter (inverter).

1. Check and, if necessary, set the sensitivity of the reference cell on SOLAR-02 consistently
with the type of PV modules which will be measured (please refer to the User Manual of
SOLAR-02)
2. We recommend making a preliminary evaluation of the value of irradiation on the surface of
the PV modules being tested by means of unit SOLAR-02 (operating independently) and the
reference cell
3. Switch on SOLAR I-Vw or SOLAR I-Ve. Check and if necessary modify the basic
settings of meter relative to the minimum irradiance threshold, the FS of DC and AC
transducer clamps, the IP and the parameters of the PV installation on test (see § 5.1.1,
§5.1.5 and §5.2)
