The more reason why you have a breaker in the Disconnect box to cut off the panels output or you install a DC solar isolator switch.

no, short circuit will not damage the panel

Schletter offer a 25 year manufacturer's warranty and the design life of the components is in excess of 30 years, so yes, the racking system is designed to last at least as long as the other components of a typical PV system.

Yes, IQ8AC and IQ8HC microinverters are available in Australia now.

The maximum solar array size that can be installed on the 6kW single phase model (the largest) is 13kW. Please refer to the link below for specification details. The AC can operate with or without batteries connected to the inverter. It can only operate without batteries if there is sufficient solar generation to supply the load. www.acsolarwarehouse.com/products/sungrow-6kw-single-phase-hybrid-storage-inverter-suits-sungrow-battery-modules/

@@ACSolarWarehouse i have read the manual. You didn't ask the questions.i asked how much kw of solar power you have on that specific experiment, and if you run it without batteries.

No, just one Envoy required.

Pricing for the Australian market has been released recently. You should contact an accredited Enphase installer for a specific quotation. enphase.com/en-au/installer-locator

Hi Timothy, 3 phase installations typically have a third of the solar panels on each phase. For example, if there are 20 solar panels, there would be 7 on two of the phases and 6 on the other. A 3-phase Enphase trunk cable is used to achieve this. In saying this, it does depend on the roof and how the installer designs it. Each phase has a CT, and you will see the sum of the energy generated across the 3 phases. Below is a link to a video which shows the operation of the App. Hope this helps. ruclips.net/video/1YCkS8pP3ck/видео.html

Hi Giuseppe, there are a few possible causes of this. We'd recommend that you contact Sungrow technical support on 1800 786 476 to resolve this issue.

I am a solar installer and was never able to simulate this. you are absolutely right, it would take a couple of ten thousand volts to simulate this with the distance between the wires he was showing. If this was true, it would be a nightmare for the transformer manufacturers... and a pleasure for the TEASER manufacturers, finally low voltage arc's, lol ... or maybe I got it all wrong, then please someone come and demonstrate me...

Same question I had, there should be a ton of DCV there to maintain that huge gap. But you know he's not handling 30kV like that obviously.

@@xorbe2 The arc starts when the wires are brought into close proximity (i.e. very close to touching ). Once established the arc is easily sustained across a gap of several centimetres due to the ionisation of the air around the fault. This is a relatively easy experiment to recreate with four common 300W -400W solar panels - so long as appropriate safe precautions are taken of course. There is no trickery involved. One of the reasons for the original posting of this video was to help clarify the common misconception that dangerous DC arcs only occur in high voltage and/or high current situations. 160 volts DC and 10 amps is easily enough power to cause and sustain a destructive arc fault.

@@ACSolarWarehouse even 2 panels will make a nice arc, and can kill you. He was silly to even do that with leather gloves.

Hi, an RCD in the circuit does not negatively impact the Envoys ability to communicate with the microinverters.

Hi Solar Expert, we've not aware of any evidence of a house fire (or even any heat damage) caused by the arc from a single solar panel anywhere in the world, as the voltage and current available is simply not capable of sustaining an arc hot enough to combust typical building materials. Inverter standards don't require microinverters to have AFCI for this reason. String inverters with AFCI can shutdown when they detect an arc, but if there is a fault between the positive and negative cables within an array (i.e. a short circuit) the inverter shutting off will not have any impact on the arc fault. AC Solar Warehouse sells a comprehensive range of AC, DC Optimised and DC solar equipment. Each technology has it's pros and cons. AC Solar (microinverter) systems are pretty universally recognised as the safest of the various solar technologies due to the absence of any dangerous DC voltages. This has certainly been our experience over the last 10 years.

@@ACSolarWarehouse a single panel can create an arc

Enphase recommend the white wire of the CT be connected to the top terminal and the blue connected to the bottom corresponding terminal. If they are swapped, it will not damage the Envoy, you will simply notice incorrect readings. If this CT is also turned around on the cable you will experience the correct readings. So if your readings are correct this could be the case? Your installer would be best to help if you are concerned.

@@ACSolarWarehouse My production metering seems correct and this is the one that is turned around but my consumption never seems to be accurate. Says I’m consuming like 80w which is super low. Using a Powerpal to check monitoring when solar isn’t producing and never seems to match up. Would have thought the Enphase should be giving the same reading as the Powerpal. Not sure if having the production CT installed around the opposite way might affect the consumption CTs at all?

​@@atanner4 I suggest raising your concern with consumption data with your installer so they can check the envoy is installed as per above.

In Australia, the Envoy-S Metered is supplied with 2 x 100A CTs. Not sure about other jurisdictions.

Hi Icloon, the new model hybrid inverters from Sungrow have natural convection cooling with an ambient operating range of -25 to 60 degrees C. In Australia, solar systems must be installed by Clean Energy Council accredited solar installers who provide a complete price for the system installed. So these are not sold without installation etc so unfortunately we are unable to advise the price of the inverter alone. Try contacting your local solar supplier. The changeover to backup/emergency mode is <10ms. You can start appliances with the hybrid inverter in backup mode, you just need to ensure the appliances do not exceed the maximum output rating of the inverter during start and run. The inverter will even operate without a battery if there is sufficient solar energy at the time to power the appliances. Specifications with the details are available here www.acsolarwarehouse.com/products/sungrow-5kw-single-phase-hybrid-storage-inverter-suits-sungrow-battery-modules/ Hope this helps

Because DC doesn't "alternate" so has not a zero-point like AC. DC is "direct" and insists to flow same direction.

The Envoy collects individual panel data via a power line carrier (PLC) connection to the microinverters. This data is collected every few minutes from each micro. The CTs provide total instantaneous production and consumption data which is used for other purposes - like export power limiting.

Hi Bionic, the pool pump is a Waterco Hydrostorm eco-v which draws 8.9Amps, the inverter is the Sungrow single phase 5kW hybrid inverter SH5.0RS and the battery is the Sungrow FFP modular battery. You can obtain more details about these products here www.acsolarwarehouse.com/products/

Sorry, we're based in Australia and the Enphase Encharge system isn't due for release here till early 2022. We'll post some installation videos when it becomes available.

Yes, the current flowing is equivalent to the Isc of the modules. The modules and cables are within their current rating, the arc forms due to a poor connection in the circuit. Once the arc commences, the heat will melt the conductors. If the arc was able to be bypassed with a solid connection, the arc would extinguish.

@@ACSolarWarehouse Quick question, i'm building my frist setup, cables from panel going straight into my lab, positive to fusebox , negative to fusebox , then to breaker then to MPPT charger/inverter. What's your recommendation, I'm afraid as I have the voltrage from the solar panel coming physically into my lab. But if you trigger off any load from the inverter no current will flow right? or I'm at risk anyways without any load

Go ahead. It won't interfere with the reading.

The Envoy collects individual panel data via a power line carrier (PLC) connection to the microinverters.

@@ACSolarWarehouse thx for the fast reply! ...i wasnt expecting any sort of wireless connection as envoys can link to such a big amount of microinverters.

There are no transient currents here as there is no energy storage anywhere, except for tiny bit of stray capacitance. Once shorted panel just maxes out it's short-circuit current, which is in a 10 A region. Also that current is not going through bypass diodes, as there is no imbalance between panels.

For our low voltages installations (mostly residential) its typically single phase, 120/240v black conductors and your neutral/ground. We use blue and brown for our 408v
