We have. There are settings inside California 21 that are adjustable within the Mode Q(U)+Q(P) settings

@Ampster thank you for taking the time to answer. Yes, that's the easy solution. I have an EV that I plan on charging to load shed above 90%. Nevertheless, I believe there are settings in the Mode Q(U)+Q(P) that should throttle down the GT inverter production without it going offline. I was...

@YellowBuddy I've ac coupled my (2) solaredge 7600 HD wave GT inverters to my (2) sunnyIsland hybrid inverters. They work perfectly. I have California 21 enabled on both solaredges to not over charge the batteries. But once 90% battery charge is achieved, the solaredges cycle offline as the...

Hedges, I wanted to thank you and give you an update. I ran my first full-scale test by disconnecting from the Grid. Everything worked perfectly. My house was being run by my critical loads panel. My PV was charging my battery. My Sunny Islands were providing the Grid to the Grid Tied inverters...

I have installed two switches between each solar edge inverter and the main service panel. The switch reroutes power to/from main service panel to critical loads panel. I can direct one, both or neither solaredge to the main service panel by flipping the switch or conversely switch one or both...

N/G is on the trailer and generator. By switching plugs, it's essential a poor man's transfer switch. Would I just set the SI to Gen/Grid setting?

I have ac coupled the Solaredges with the Sunny Islands in a critical loads panel. I still need to change the Solaredge settings to California 21. Unfortunately you need installer rights to have access to those settings, So I'm working on that right now. Once I have California 21 enabled, I'll...

Hedges, in your vast helping of others, thank you again by the way. I have a 2 part question. Part 1, have you seen if simply activating California rule 21 on the solaredge inverters is enough to activate frequently watt shifting between SE and SI? I found this video, at the end it talks...

I have no need for more GT capacity. My system is 14kWp. Running 2 Solaredge 7600 HD wave GT inverters (plenty of excess capacity) coupled with 2 Sunny Island 6048 Hybrid Inverters. 960 AH 48v battery bank. My Solaredge are both California 21 capable. Because the Solaredge and SI can't...

Looking for advise from anyone currently using solaredge HDwave inverters for Grid tied PV. I have successfully AC coupled 2 sunny islands through the critical loads panel with a manual transfer switch. My last step for battery backup in times of grid failure is to throttle my GT PV when grid is...

Thank you again Hedges. I already wired a 50 amp plug outlet with 6awg wire (3 foot run to bottom of the panel) if I went 70 amp, would 6awg be beefy enough? Additionally my cables and plugs are 6 gauge cables. If passing 56amps I feel 6 gauge would be fine. I do want to keep the trailer...

The generator in the diagram is the same generator setup that came with the trailer. Currently the generator feeds the two SI through a 6awg 50 amp twist lock cable into the back of the utility box. The SI then charge the battery from the generator. So it appears if I want to use the generator...

Thanks Hedges. So to be clear remove ATS between main panel and critical loads panel and install an interlock breaker that allows only the grid breaker to be on or the Sunny Island to be on, but not both at the same time. This would require a manual switch at the panel in case if grid failure...

Hedges, I'm getting closer to buying all my parts for this project. I keep getting conflicting advice about schematics. Can you please review this (pdf) and see if I'm nearly there? Page 1 represents the current Grid Tied install while Page 2 represents my proposed AC coupling add on with my...

Hedges: Sorry for ongoing questions. I keep getting different advice from different sources. One source is telling me that if I want to backfeed the grid (net metering) with my current PV setup (solaredge) but also want the power my trailer is generating to add to my netmetering balance, I need...

What if I have a generator as the backup to my batteries, but the generator only recharges the battery bank but doesn't directly feed the inverter. I'm assuming I'm still safe with no load transfer switch

Hedges: Does the SI 6048 need an Automatic Transfer Switch between the Main Service Panel and the Inverters? I thought I read somewhere that SI's could detect grid failure and switch on their own without a transfer switch.

Hedges: Thank you again. I think this shows the feature exists, I will explore it more. https://www.solaredge.com/sites/default/files/application_note_power_control_configuration.pdf Page 11

This was the correspondence with this solar engineer. My question (I borrowed from you, not likely very well) His Response

Hedges would this imply yes Solaredge does support frequency watts? https://www.solaredge.com/us/products/power-optimizers#/ The UL 1741 SA certification ensures that inverters stay online and adapt their output to stabilize the grid during abnormal operation instead of disconnecting. This...

Hedges: I was at a 'be prepared' (emergency prep) convention and a solar engineer had a both. Very friendly and knowledgeable guy willing to offer advise. He cautioned me on using the solar trailer on my current setup based on my GT solaredge inverters. According to him, the Sunny Island...

Hedges: The good news. I replaced the old slave that had the tempsensor error. Added the old SD card, ran setup and designated it as S1 and everything works like a champ. I did some research and found someone who got further in the support conversation with SMA and they said their issue with...

Hedges, thankyou. If I were to try to designate the current slave as master and current master as slave, are the Master and slave interchangeable or would I have to reroute any wire or cables, besides the battery sensor from the old master to the new master?

Hedges: As I replace this faulty slave inverter, how many settings do I need to specify in the quick startup? If the slave is getting all its orders from the master, do I just need to designate it as a slave or do I need to specify led acid battery, size of battery, 48v, etc.? Also if each...

Thank you again Hedges. This is my next stab at this, I'm hoping I am a little closer but probably still have errors. If you have a moment to correct and instruct, again, I express my gratitude.

Hedges: This is my first attempt, feeble as it may be to try to illustrate what I would need to do. Could you tell me how close or more likely how far off I am on this diagram?

It appears they use power optimizers https://www.solaredge.com/us/products/power-optimizers#/

My two SolarEdges are configured with inverter 1 with 21 PV with South Facing exposure inverter 2 with 7 PV South, 14 East, 6 West Inverter 1 output yearly is 985 kWh Inverter 2 output yearly is 665 kWh I know when we installed my PV system, we intentionally left plenty of load margin off...

@Hedges, I had the same question for the SMA support staff. Why would a slave error out on a temp sensor that is connected to the master? They said they were connected and if it was faulty it could trip the slave, but I really don't know. I suspect the unit is totally fine. I sent them the...

Hedges: Thank you. I see you having replied to many posts. I really do appreciate your expertise. My SolarEdge inverters are UL-1741-SA authorized so that will work well. I have a 400 AMP main electrical panel on my house, It wasn't much more expensive than a traditional 200 AMP box. However one...

I purchased a DC solar trailer I'm sure some of you are aware of as many have been purchased. Before using the trailer, I boiled and balanced the 48V led acid forklift battery bank and the batteries are as good as new. I've seen many demonstrate how the 10 235 watt solar panels, are...
