The generator surges on both gasoline and propane. It only surges under load. I was not able to stop the surging by careful adjustment of the main propane tank valve or any other adjusting screws. Is it possible that there is a problem with the governor? If so, how can I trouble shoot the governor?

Went to the transmitter site today. I did not have time to work on this issue; the snow chased us off the mountain! I guess I will have to re-open the topic later when I have more time to chase it down. Thanks for standing by!

Watchpower (LV6548) only reports intermittently lately. Can anyone tell me why?

Still waiting for weather to improve to go to the transmitter site but I want to keep the topic open.

you bring up a good point; I don't think I disconnected the A123 bank from the system when I checked the voltages. I will try to absorb your input and check all my parameters on the controllers and BMS's before a trip to the transmitter site tomorrow.

Thanks, Vigo for your insights. I don't think a picture would help much in this situation because of the cramped nature of the equipment room but the 2 banks are wired in parallel to busbars ahead of the 2 LV6548's. The cables to the A123 bank of batteries is a couple feet longer though...

We have a system similar to yours. We elected to remove the N-G bond screw from only one of our LV6548's and from the A-C electrical panel. This is working for us and we are using 240 volts. We use this system to power an FM radio station and we do not notice any RFI interference in our...

So, we added a rack of 6 EG4 48v batteries in parallel to our A123 bank of batteries. The LV6548s only seem to be drawing power from the EG4 rack. The EG4 rack is at 52.27 V the A123 bank is at 52.21 V. Why is it only drawing from the EG4 batteries?

Yes, the warm water system uses power and that is a concern if we become snow-covered for several days or something like that. We are still working on making the system bullet-proof but it is getting more and more complex. We have 12 kW of solar panels and 32 kWH of battery capacity with 2...

to answer sunshine_eggo: at full power (1000 watts output from the transmitter plus a few other pieces of equipment) it draws about 1700 watts, 24/7. Our 30 kWH bank of batteries can't get through the night at 1000 watts transmit power so we have been lowering power to 200 watts at night. We...

Ellcon123 - please explain - what is "OP"?

Is Signature Solar a reliable source of lithium batteries? Does anyone have another suggestion?

Thank you for this advice. This is very helpful. I will try to apply this as soon as I can.

thank you so much for your advice. Without the help of this forum I don't think we could have gotten this far. When "those who know" sacrifice their time, energy and experience for "those who don't" it gives me hope for humanity! Our project is powering a small radio station on a mountain, 2...

Sorry, I dont know if I have a pre-charge circuit, do you mean for the BMS or the LV6548? The PV would charge but it does not "see" the batteries because the BMS has them cut off. Can I permanently attach a AA battery to the BMS so it never shuts itself down?
