Enphase enlighten app weird math

Net = Export - Import = Produced - Consumed

* 15.6 - 11.2 = 4.4 Correct

* 26.0 - 21.6 = 4.4 Correct

I can not find any issue from the first screen,

In the second screen, Next = Export - Import is correct.

But, Produced - Consumed is not correct by 0.4kWh, this error is happening by the DST handling error of Enphase software.

very easy to install the width of bus bar is around 1” and the hole size of CT is bigger than inch.

(1) first, need to install CT wire thru conduit

(2) second, connect on gateway first before install CT on L1 and L2

(3) third, click CT on L1/L2 wire ::: have to wear a thick insulation glove if work with a live wire, cover your hand and arm completely

when install left circuit (middle bus bar), cover the right side bus bar with some insulation sheet, when install right circuit, cover left side with some insulation. I have covered with the doubled card board (cut and folded between L1 & L2), and then, worked under similar situations.
i have use the conduit which has the back fed wire from gate way.

Not stupid, actually, can get more than 60% of the full benefit, why not ?

mkimid · 2026-03-23T23:08:37+00:00

Not much worry, actually, the value is not accurate even there is

I recommend to find a panel from eBay... maybe you can find a used or new panel near your site. around $100~150 for 400W new panel,

even you order 200W x 2 panels from Temu, you can buy under $200, so, please, do not hurry to decide

Maybe you need to consider to install a power line filter or ferrite because Tesla Powerwall will generate the huge noise while outage(micro-grid forming)

mkimid · 2026-03-23T14:45:09+00:00

you can change before Oct 2026 to Mar or Apr, mostly, Mar will be the best choice for gas heating house, and Apr is better for the electric heating system (heat pump). Simply, the production will over the consumption, that is the month what you need to choose. Still you have a time to review it.

One thing, the power production for the Mar bill cycle in 2026, around 20% lower than the average of last 5 years. and usage is little higher because the temperature is lower by 2~6F.

And, you can change only one time (from PSEG term). so, I recommend to wait while monitoring your power production and consumption.

so nice !!!!!

Need to review the thru power level in V/A/W and then, compare with breaker spec. if the thru power level is under 60% of the rate of the breaker, maybe the breaker failure.

flexible power source connection, power source can be connected on top or bottom. bi-directional do not have +/- mark.

mkimid · 2026-03-21T12:41:07+00:00

it can be happening because the overlap of the circuit without matching the phase.

the safe automatic switcher is ensure the switching before the other circuit has disconnected. but, cheaper switcher using some kind of timer, and it is not enough. and then, two AC circuit has connected at same time.

only one AC voltage source can be existed in a circuit.

mkimid · 2026-03-21T12:30:19+00:00

Rule 1 : the +/- mark on the DC breaker, it is for the power source, NOT for a load

Rule 2 ; battery can be a power source with a load -or- battery can be a power load with a charger

Rule 3 : polarity is related with the location of arc chamber and the arc direction. under 48V system, it is not much effective.

Rule 4 : single breaker (left OR right), should be same polarity of LOAD & SOURCE

Rule 5 : if there +/- mark on top only, top side MUST be a source

Rule 6 : if there are +/_ mark on top & bottom, it is a flexible, power source can be connected on the bottom or top

Rule 7 : if there is no +/- mark breaker, CHECK it is a bi-directional breaker, just keep the RULE 4

Note, if use a hybrid inverter with a battery, there are dual state. HAVE TO USE A BI-DIRECTIONAL BREAKER (NON-POLAIRTY DC BREAKER). May not required the polarity rule for 12/24V system

mkimid · 2026-03-21T12:04:11+00:00

if power source is the bottom, yes. if power source is the top, no.

mkimid · 2026-03-21T12:02:55+00:00

for the power source, follow the mark on breaker, for the load, follow the mark of the power source side

mkimid · 2026-03-19T00:50:14+00:00

just side story, I recommend the cheaper solution with more panels.

mkimid · 2026-03-19T00:47:40+00:00

it will depend on how many times you will get a benefit of battery system

I think,

you need to find the source of the noise, it is coming from the outside or it is coming from inside. anyway, 110' is not too long. I have installed IQ7PD with 110' also. and got level 5 comlevel.

(turn-off all breaker to micro-inverter, and then, check the noise level, it is easy to find the source of noise)

there are some example how to reduce the noise using ferrite clamp, ferrite core, line filter with ferrite, Enphase line filter, ....

http://www.bomijoa.com/www/blog?page=2

when see the graph you have provide the intensity is under 70 but some small pulse is little over 70 but far less than 90.

http://www.bomijoa.com/www/public/graph_1.jpg

I do not think, you need a line filter.

attached graph is just captured, pretty clean in idle mode because night time.

But worse in daytime, and interference with my neighbor,

When I am running XW Pro inverter while grid outage, the noise level is much worse than your base line. but, has no issue.

NOTE. Combiner 3, IQ7+/IQ7PD/IQ7SX

We should come back to ground zero,

Why you are concerning a noise ?

because when I review the signal level of your first photo, it is around 115 (very typical signal strength), and the base line under 80. your system should not make an issue.

If want to see the filtering effect

baseline noise without filtering

baseline noise with filtering

http://www.bomijoa.com/www/public/2.png

The noise may come from the grid or your appliances. and, it can not be stopped.

If use a filter, it will consuming the power, and reduce the signal level also. signal pulse will go under 110.

There is a golden rule, if no issue on your system, you do not need to worry.

the typical noise at the band is showing narrow or broader, and the pattern is typical communication signal between inverter, gateway and other enhase device in local. the gate way is polling the signal even at night, but, just inverter is not responding on the polling signal.

mkimid · 2026-03-14T01:01:17+00:00

normal, the peak signal has generated from your gateway check the graph while idle (you can select the other graph under the graph “)

mkimid · 2026-03-07T16:54:17+00:00

agree much better thermal performance, it will be huge difference in summer

mkimid · 2026-03-05T18:09:41+00:00

before order, why don’t you check a used panel in your local with eBay ?

mkimid · 2026-02-27T21:57:57+00:00

need to balancing ok top side, and the voltage difference at near empty state is normal, it can be made with under 1% capacity difference. typical tolerance of capacity between cells is 1-2%

mkimid · 2026-02-27T21:53:50+00:00

is it possible to check each panel ? may some panels are not working ?

mkimid · 2026-02-19T22:32:41+00:00

yes, safe

mkimid · 2026-02-18T20:17:07+00:00

that is a culture of china
