Jesus, I will have a lot of questions about the system, so we may want to move over to our tech support system, but we can start here. You can either respond here, or send your responses to [email protected]

• How are the batteries being damaged?

• What is the manufacturer and model number of the batteries?

• How many batteries are there and how are they wired series / parallel?

• Is the Hydro the only charging source?

• What voltage is the hydro outputting / What is the maximum current the hydro is outputting?

• How are the 8 switches set on the TS-45?

  Thank you

Thomas, Sorry for the delay in getting back with you. So grounding is an interesting subject. Some say that if you discuss grounding with 2 subject matter experts then you will get 3 opinions of how it should be done. In your circumstance I would suggest to either leave it all floating, or ground it as I described with having the battery negative tied to the camper chassis, as well as the Inverter Earth Ground connected to the camper chassis. I would not tie the Inverter Earth Ground Directly to the Battery Negative. For the Remote on/off switch you would not be able to use a Lighted Switch, there would not be enough power to illuminate it. The switch is just creating a short or an open signal with very little current flow. As to the wire specs for the newer Inverter, the older classic has a Longer Runtime for Surge and thus calls for a larger wire.

Also, a great resource for all things grounding is a gentleman named Mike Holt. You could find him via google search as he has books etc, he also has a youtube page at the link below

Larry, The EMC-1 is intended to be a 1 to 1 device. The EMC-1 will "poll" Modbus IDs from 1 - 247 looking for device that is connected to it and it will Logically Connect with the first device it finds, typically device #1. If multiple devices are connected, like you have via the meterhub, then the EMC will connect to the first device it finds and you would be able to see the Liveview Webpage for that device, but not for any of the other devices. As you have indicated, if you have a Modbus program that you can send commands to a specific modbus address, the EMC will route that traffic and get a response form the controller tat was addressed. We do have a new product on the horizon, ReadyEdge, that can be a 1 to many device

Thanks for the timely response Pete. I recently noticed the ReadyEdge; I'll check that out.

Mike, Are you using the EMC-1 ethernet adapter for your remote access? It may be best for us to have a conversation on this as there are likely many ways of accomplishing this. Could you email your contact info to [email protected]? Thank you

Thanks for the detailed reply. I have limited ability to remotely manage loads on the battery bank. I will implement a remote start for the generator (which powers a charger). However, I need a foolproof way for the solar controller to recover. I'm surprised that the TS-MPPT has no ability to sip power from solar panels and reboot the system.

Battery sizing, LVD settings, and in some cases generators or other alternative charging sources almost always makes it so dead battery recovery is not necessary. However, I understand that there are some cases where it must be able to recover from total discharge.

Another option if you have a 48V battery, is to add a separate nominal voltage PV string and add a TriStar PWM controller set for diversion control mode.

Alternatively, adding a single lower voltage module with a power diode to prevent reverse current would be able to wake up the controller. If this is for a lithium battery there may be other considerations.
