8 System Control
Parameter
Description
MppPwrTempCoeff
Power temperature coefficient of the PV mod-
ules. Use the PV module datasheet as a refer-
ence.
SafePctPv
Base of MPP power which will always be
available in case of PV drops in percentage
of current MPP power
CalcPvPwrAtMpp
Estimated MPP power
Requirement:
☐ You must be logged in as Installer.
Procedure:
1. Go to Control Functions > PV control functions > MPP calculation via the page and menu selection.
2. Set the desired parameters (see Section 4.8.3, page 20).
3. Make sure that the parameters MppNormOpCellTemp and MppPwrTempCoeff are set in accordance with
the technical data of the PV module (see manufacturer documentation). Setting the parameters
MppNormOpCellTemp and MppPwrTempCoeff in accordance with the technical data of the PV modules
enables a reliable estimation of the PV power from the Fuel Save Controller.
