You could buy a monitoring system like Emporia Vue with a couple of CT's around leg 1 and leg 2 wires coming into your main panel to see if you are exporting. My smart meter is able to read not only the kwh incoming into the house, but also reads and documents the amount of kwh exported. I'm...

Perhaps a focus on powering a window AC unit alone is a little too narrow. Need to look at least at your base power load requirements and determine what your critical circuits are. Once that is understood, you might consider a manual transfer switch and a small inverter (possibly starting out...

May be a technicality, but it would appear to me that an off grid inverter can export electricity if the grid is down ... if it is wired through a sub panel that is connected to the main panel (or to the main panel directly) and the breaker is on and there is no interlock kit. This is what...

Looking to see who out there has an EG4 6000XP that is running a fairly large and variable 240 volt loads from a 3-5 ton AC and blower with a soft start. Just some basic info like how long you've been running the EG4 6000XP this way, general location (state/country), daily kwh consumed by...

Thanks for the help.

Thanks

,Yes. That's right.

5/16" lugs on both ends - 5' or 7'

Anyone find some good 2/0 battery cables from Amazon that have performed well and are a good value?

@FilterGuy, if I hardwire the ACout to include ground and neutral (in addition to the two hots) into the ProTran2, can I just wire the two hots on the ACin and forgo the ground and neutral?

Is the wiring recommended by @FilterGuy for the ProTran2 any different for a subpanel that shares the neutral and ground with the main panel but is isolated from the grid with a breaker off or an interlock?

It might have been mentioned in the above replies, but make sure you understand what the inrush of current is required to start the heat pump. You can install a ~$400 soft start to reduce that significantly. On my 4 ton heat pump, I went from an inrush of 120+ amps to under 20 amps (at 240...

I normally use an EG4 3k all in one inverter with a manual transfer switch to power a few circuits in my house and everything checks out ok. I recently used the inverter with batteries at another location to try and power a refrigerator. I was getting a blinking LED when I plugged in the...

Given that solar panels degrade 2% in the first year and then 0.5% per year thereafter, I’m wondering if this results in any decrease in Voc or if it only affects the amperage.

Never mind. I had a problem where the inverter grid voltage needed to be set higher.

On heavy dew days overnight, I get a substantial dew on the solar panels and the inverter startup time is delayed. Seeing it more in the fall/winter months as I'm getting the sun shaded by trees more this time of year. Yesterday the inverter started up at about 8:30 am. Today it still has not...

So what happens when the battery becomes iompletely charged, the PV array is generating peak power, but the load is minimal? Would you have to change settings for no export control and have a smart meter installed?

My solar generation has fallen off significantly due to tree shading at different parts of the day. I have very tall pine trees which don’t shed much needles in the fall/winter. PVWatts was very accurate in August, but September was a little lower by 10%, October 25% lower, and November was...

I’ve got a Growatt 10000 watt grid-tied inverter with 4 MPPT’s. I’ve currently have 10 400 watt panels with about 300 volts on a 4/12 pitch roof on one string going to one MPPT and 4 400 watt panels with about 120 volts on a 8/12 pitch roof on a second string on a separate MPPT. Both are on the...

Thanks. That's exactly the feedback/data I was looking for.

I have Emporia Vue installed and therefore have the instantaneous measurement of solar and know I have shading problems. What I don’t have is a year over year comparison that would shed some light (no pun intended) on the number of cloudy days from one year to another. Seems like I’ve had 2-3...

I’ve only had a 4.1 kw (10 panels) grid tied system running since August. I had very comparable results in power generated vs PVWatts in August but have been running significantly lower since early September. Some of the deterioration into the fall is a clipping due to the sun not rising as high...

I’ve got 10 panels on a 4/12 pitch roof and an additional 4 panels higher up on a 8/12 pitch. All are facing south. Is there some program or app that would tell me if it would be more optimal to run them separately in two separate series or if it would yield similar results to run them all in...

It seems to me like they are not a bargain if your planning on getting a tax rebate. IRS rules require purchases to be new equipment only. Best to stick with new!

I have 14 CS 400 watt solar panels in use with a grid tied inverter but have an EG4 3k off grid inverter as a backup if I lose grid power. There are no issues with the array VOC now (520 volts) with my grid tied inverter and I don't expect any during the winter (560 volts), but I could have an...

Are you saying people wired hot on neutral on ACin?

That’s what I suspected. Seems like the manufacturer could alter the software in the AIO to only allow the ACin (generator power) to charge the batteries and/or allow pass through of converted DC power (as well as solar and batteries) to power the loads, and not allow bypass of ACin power...

I’ve heard a few people say that the EG4 Chargeverter cleans up the dirty power from a non-inverter generator. I thought I remember people saying it’s the same charger that’s in the EG4 AIO’s. I realize that EG4 AIO’s have been fried when the ACin has been from dirty power from a generator. I’m...

I used 4 400 watt Canadian Solar panels in series with mine which produced voltage just right above the threshold and did not see great performance. I did just have them on the driveway temporarily with a little tilt but sub optimal but I could have used a 5th panel and I think the results would...

Do you mean UPS mode and not USB mode?
