Fig. 3: Connection of MPP300 for testing a three-phase PV system
 When SOLAR I-V is set in order to use MPP300 as a remote unit, ALL
connections relevant to electrical quantities (voltages and currents) must
be carried out on unit MPP300. SOLAR I-V must have no voltage nor
current connected to its inputs
 The maximum voltage for the inputs of MPP300 is 1000VDC between
inputs VDC1, VDC2, VDC3 and 600VAC between inputs VAC1, VAC2,
VAC3. Do not measure voltages exceeding the limits given in this manual.
Exceeding these limits could result in electrical shocks to the user and
damage to the instrument
 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-V, check and, if necessary, change the settings relevant to the type of
remote unit, to the minimum irradiation threshold, to the full scale of the AC and DC clamps,
to the integration period and to the parameters of the system being measured (see the User
Manual of SOLAR I-V)
4. In order to guarantee the operator's safety, disable the system being measured by means of
the switches/breakers upstream and downstream of the DC/AC converter (inverter)
