Re: Where To Combine PV Strings

I considered AC Coupled.... I was not sure how well AC Coupling works, since the Inverter is trying to "trick" the SolarEdge into working. Do you have expericence with AC coupling? Yes i have had very good luck with AC coupling. I am AC coupled to a Solaredge 3.8 kW inverter and 4 Enphase IQ7s. If ...

Re: CANBUS interface

For starters all I would need is a "stop charging" command that I could probably program an Arduiono to send.

Re: CANBUS interface

Thanks for the link. I may not have phrased my question correctly. I understand that CANBUS is the network protocol. What I need to figure out is the language that my Skybox uses and how it could talk another device on the CANBUS network.
Maybe I am askingt if there is a Library of commands?

CANBUS interface

Does anyone know of any documentation of the CANBUS protocol? I know Outback has developed some in conjunction with SimpliPhi but those are all proprietary. Is there a vocabulary of commands? I have an Orion BMS that has two CANBUS channels and I was interested if there is a way to have the two comm...

Re: Where To Combine PV Strings

....... Can I combine the 2 strings out by the panels and only run only 1 line into the SkyBox? ...... Also, I see that the Skybox can use the Tigo TS4-S-R for rapid shutdown. Will the Tigo TS4-A-O work with the Skybox so I can have optimization on the panels? I can try to answer most of your quest...

Re: Compatibility with SolarEdge Rapid Shutdown Optimizers?

Ah, I was thinking if the SolarEdge inverter was in the critical loads panel there wouldn't be AC coupling. But, now I get from the SolarEdge inverter's perspective all it would see is available power and wouldn't know there isn't power from the grid. I assume the Skybox has no issue with power bei...

Re: Compatibility with SolarEdge Rapid Shutdown Optimizers?

@Ampster: If the OP wants to AC couple a portion of his existing array with optimizers to the Skybox, it should work. I believe the incompatibility Skybox has with optimizers is only if they are on the array modules connected to the Skybox PV input, not those AC coupled to the critical loads/AC out...

Re: Compatibility with SolarEdge Rapid Shutdown Optimizers?

@SoCal Dave I haven't heard back from you. I just want to make sure that you understand that Solaredge inverters are capable of AC coupling to a Skybox. My feedback was not about the compatibility of the Optimizers. My suggestion about the critical loads panel is how any AC coupling scenerio would b...

Re: Battery arrangement/wiring question.

FWIW, I'm a far bigger fan of "bottom balancing" lithium cells than of "top balancing". .............. Without some form of BMS, bottom balancing is the only safe(ish) approach to cell maintenance. Do watch the cells closely and leave plenty of headroom for the inevitable variations in capacity, an...

Re: Compatibility with SolarEdge Rapid Shutdown Optimizers?

I definitely don't want to remove the optimizers. I thought I remembered reading the AC coupling from the Skybox could drive an inverter. I guess I must have misunderstood that. I wouldn't want the inverter only on the critical loads panel. For my system, it seems the Tesla Gateway would be best. S...
