Appendix A Options and use
A.1 Boost module
The pumping VFDs ≤ 2.2KW support the installation of the boost module (PP100-3R2-PV) to
improve the utilization of the solar modules. The figure below shows the wiring method.
1. Connect PV+ and PV- of the boost module to the positive input terminal and negative
input terminal of the modules respectively.
2. Connect the output terminals (+) and (-) of the boost module to the input terminals (+) and
(-) of the pumping VFD.
3. Connect 422-communication receiving terminal RX of the boost module to
422-communication sending terminal TX of the pumping VFD. Connect
422-communication sending terminal TX of the boost module to 422-communication
receiving terminal RX of the pumping VFD. Use twisted pairs for wiring.
4. If the wiring is connected, switch on the breaker Q1 at the DC side for automotive
running.
