Re: Charger/Generator Issue

If you want to understand the dynamics of the inverter charge cycles, download the FXR (or Radian) operator manual. In the FXR manual, pages 29 - 35 lay out the logic of the charging cycles in detail, with concise illustrations. A quick study will clear up any questions. :lol: :lol: :lol: Pro Tip: I...

Re: Inverter over temp, why / how?

By slightly wonky I meant there was a breaker that I thought might be intermittent on one leg. That's been replaced. It is provided by the local utility and there's nothing apparently out of whack about it. We checked it as best we can with a DVM by seeing that the two legs were each the same volta...

Re: Connect new FM60 with old MX60

I have two Outback MX60's in my system. One is with a bank of 12 125w panels and the other with a bank of 24 125w panels. The one with the larger bank will not come out of snooze. Every time I hit wake it goes through waking, sweeping, sleeping, and snooze. Never produces an output. PV coming in is...

Re: Battery Bank Revitalization Effort

Before restarting charging, take the SG readings, just so the electrolyte is not bubbling up on you and the equipment. Not to sound contrarian, or pessimistic, but a lead acid battery that has been in mostly partial state of charge for extended periods will have built up a very thick crust of nearly...

Re: Battery Bank Revitalization Effort

Adding my 2 cents' worth here because no one mentioned battery water level. Perhaps it goes without saying but before and during a prolonged equalization charge it is absolutely essential to monitor water levels and add as needed. There will be a lot of off-gassing and levels will drop. Yes, absolu...

Re: Battery Bank Revitalization Effort

OK. The generator is connected to the inverter and is charging the battery. The settings should provide for charging the battery. Note, however, the maximum charging rate for the inverter charger is roughly 35A DC (14A AC maximum.) It will take a very long time to overcome the sulfate crust on the l...

Re: How are you charging your SimpliPhi battery?

If both charging systems are employed, whichever is leading the dance at termination voltage seems to be fine. I would agree for an off grid system where the only way the inverter would be charging a battery is if the generator is running, and in that case you really don't care what the charge sour...

Has the specific gravity in every cell in the battery been tested?

The generator is connected to the AC input of the FX3048T, correct?

What are the Battery Charging settings for the inverter's charger?

Re: Generator hook-up not working

Just hanging there, AC IN is disconnected, (and that's a good thing for safety). When the AC IN circuit is energized, it connects to the inverter.

I'd start by opening the plug and giving the wiring a quick inspection.

Re: Inverter over temp, why / how?

The Radian documents list the transformer overtemperature events (in part) as: 120°C - charging is limited 125°C - overtemperature error. The transformer is getting overly hot, certainly. The inverter charger is powered by an external AC source, such as Grid or Generator. The AC Input and Current Li...

Re: Need a new MPPT

A 24V system is a reasonable compromise. Outback controllers require array voltage to be 1.5V above battery voltage in order to charge, so can work pretty close to the edge. The FM80 can handle 80A x 24V ~ 2kW nominal PV array. Do you think I could get away with an FM60 with 1600w of panels at 35v?...

There are no MPPT controllers that I am aware of that will boost PV array voltage to charge a battery. It sounds like re-evaluating the component mix is in order.
