Re: [RE-wrenches] Is There an "Off-grid" (i.e. constant voltage) Version of Microinverters?
I'd be curious if they have any type of online monitoring, at least for the grie-tie versions.

Hi Peter, My Cybro experience was from maybe 10 years ago; at that time, they did not have any 485 connection or Lithium connection.

Re: [RE-wrenches] Is There an "Off-grid" (i.e. constant voltage) Version of Microinverters?
I presented a paper several years ago outlining a similar system using one thermal water heater and comparing it to a PV-based system. In my tests, the PV-system outperformed the solar thermal system in energy per square foot of collector. There were sometime the Solar Thermal would out perform at midday and bright sun. But not for the whole day the PV system would always win. The trick was operation of the thermostat, the Cybro made it possible to use the normal switch. The other method for switching was a capacitor across the terminals.

This is great information folks. It looks like Cybo has most of the load scenarios covered. I have one last question before I call them on Monday morning: "Do the Cybo inverters support LiFePO4 batteries? That is, does one of their four DC inputs not only auto-detect batteries but does it recognize LiFePO4 vs. PbAcid? It is my understanding that LiFePO4 batteries need a different charging cycle compared to PbAcid to attain a 100% SOC. - Peter Peter T.

Re: [RE-wrenches] Is There an "Off-grid" (i.e. constant voltage) Version of Microinverters?
yes, there are three versions of the cybo inverter, the one that I a most familiar with produced a 60 HZ AC signal; the voltage did not exceed 120 volts or 240 volts. The voltage out times the current out was equal to the voltage in times current in. This allowed me to operate a resistance load, like a water heater.

I would like a microinverter that makes available 120 Vac (or 240 Vac but 120 is preferable), 60 Hz. I would then take the output of these microinverters and combine them in a subpanel. I do not have a need for battery storage. I can explain more about the application to anyone who has an interest. Does such an component exist? Thanks in advance for any help. - Peter Peter T.
