Hello Community,
I am wondering about the documentation of the Multiplus-II GX.
There is mentioned: "... 9.5.3 Programmable analog/digital input/output ports. The product is equipped with 2 analog/digital input/output ports. ..." it made for me the impression it means I can use... mentioned in Appendix A - J Terminals
- 12V 100mA
- Programmable contact K1 open collector 70V 100mA
- External ground relay +
- External ground relay –
- Aux input 1 +
- Aux input 1 –
- Aux input 2 +
- Aux input 2 –
- Temperature sense +
- Temperature sense –
- Battery voltage sense +
- Battery voltage sense -
5./6. Aux Input 1 and 7./8. Aux Input 2 as input and as well as output? Some how convertible? I think not. Stupid thinking, isn't it.
But I wanted to be sure. Therefor I ask. So does this phrase simply direct to the only two available outputs K1 and relay?
I am somehow confused because in the VE-Config, assistant for relays is mentioned "Solarbox auxilary relay AUX 1,2,3 and I couldn't find some information on "Solarbox".
The reason why I am asking is, because I want to control my grid based AC PV inverters in three steps, when battery SOC goes over certain values,
for example a) above 90% | b) above 95% | c) above 99% SOC
- a) reduction to 60%
- b) reduction to 30%
- c) reduction to 0 %
Than it would be suitable to have three outputs. What do you think in general about my idea of controlling a different AC based PV inverter brand than a fronius in this manner ? i think it will work with two steps as well.
Hope for your help, ideas and suggestions. Thanks in advance.
