Re: Optics RE readings not matching up with Meter Readings

Wish I had a meter that would log the useage I have the older discontinued version of this product: https://emporiaenergy.com/how-the-vue-energy-monitor-works/ The earlier version cost about $100 & came with 8 - 20A CTs plus 2 - 50A CTs. I don't know the price of the newer version but with all the ...

Re: Optics RE readings not matching up with Meter Readings

My understanding is that the "To Grid" data on Optics RE represents only the power that goes from the inverter that is sold back to the grid. It does not include power going to any other place, such as batteries, or the load to power appliances on the property.  These systems have no way of knowing...

Re: Westinghouse WGen9500DF Dual Fuel Portable Generator

No. The key fob start is for starting the generator from a distance, just as you use a key fob to lock and unlock your car from a distance. You could do this but you'd have to leave the generator connected to Skybox all the time and it would be manual start only, not via AGS. In order to use the Sky...

Re: In Ac Voltage too high

Is there a way to adjust the maximum ac input voltage from the grid in mate 3? It seems to be set at 250V as that is when my system disconnects from the grid and gives me an ac input voltage too high error. I live in Nicaragua and the voltage here can be quite volatile. I dont mind upping the volta...

Re: Using 1 FM60 and 3 FM80s in a system

Raysun mentioned float coordination in an earlier post. I think it might be worthwhile for you to try enabling it (if it's not already) to see if that keeps all your chargers working together. Here's an excerpt from the Mate3s programming manual re float coordination. https://drive.google.com/file/d...

Re-Bulk Voltage is at the Default: 48 VDC
Since your battery only got down to 49 volts your inverter never reached the rebulk setting. If you want it to charge from grid when battery gets down to 49 volts the rebulk must be at least 49 volts.

Re: Inverter was not connecting to the grid to charge the battery

What is your inverter's rebulk voltage setting? If it is set too low your inverter won't start a bulk charge.

Re: Voltage spike ?

Your inverter will pass thru whatever AC waveform it sees to your loads, so any problems will more likely be with your appliances rather than with your Outback equipment. Note you should be able to program your inverter to reject both low and high, AC in voltage. Here's how mine is set up:https://dr...

Re: GVFX3524 Setpoints and No sell energy

I've had my 2 GVFX3524 inverters since 2007 and they have served me well in a grid-tie/battery backup system. As long as they hold up (getting long in the tooth by now), you should be happy with them.

Re: AC hot out function question for newbie

IEEE 1547 specifies OV1 as 132 VAC and OV2 as 144VAC, so you should be able to bump it up to 132V at least.
It's not settable. 130V appears to be the setpoint for IEEE, at least that's the point where it clears.

Re: AC hot out function question for newbie

Good point. The same thing (or worse) could happen if a grid-tied system is selling with the float voltage "adjusted" to the bulk setting after charge parameters have been met, and for some reason selling stops - like for a grid outage, or if grid voltage goes high and the inverter stops selling. Th...

Re: AC hot out function question for newbie

If your selling something, the first thing to check is your sell voltage. On OpticsRE go to the inverter -> AC input. Try a "sell voltage" that is ~1.5V below your float voltage. Not to butt in here, but might be better to set your sell voltage at your desired float setting, and raise the float set...

Re: Can a VFX3648 be mated to a GVFX3648?

The GVFX especially will not work. In fact, that was the first of the Grid Tied models, and is somewhat fussy even in its designed usage. IIRC, they don't work well, if at all, off-grid. Ray, don't know why you're saying that. In my experience with 2 GVFXs, they work fine during a grid outage, and ...

It seems to me a more immediate solution would be widespread adoption of electric vehicles, which would mostly be charged at night.
