Anyone has an european wire diagram ?

Not too sure what you all have said. Over here we tap either L1 & L2 with a neutral to get 120V. The phase voltage between L1 & L2 is 240V that the inverter comes up with. Does that mean the Asian and Europe equipment would generates the phase voltage of 480 v between L1 & L2? Is the difference...

Europe and Asian 240V PV equipment VS Us's 120 V I have a small DIY off-grid system. In addition, a friend who help me to built a solar structure to install my grid-tie Enphase PV system. All work well and he was impressed. He has a home in Vietnam and is interested to do a diy off-grid...

Smart way to use a bad panel for good use to create an aesthetic view of the roof!

I have a PV system with 1.92 KW Solar Panels, a Growatt 3000SPF ES Inverters and EG4 5.12KWH battery. Don't know why the Battery SOC lights only 3 out of 4 lights light up when the voltage reach all the way to 55.8V which is already 100%. Never goes higher. I only see it went above 55.9...

Does anyone have the above 200A MSP manufactured just over 10 years ago by Murray, now owned by Siemens? It came with a 4-pole 200A MEQ9985 breaker, and because of 120% rule to connect more than 40A of solar back-feed breaker to the MSP, you need to de-rate the main breaker. Siemens said the...

I was in that mentality when I first wanted to do a DIY Solar and I thought 600W or 1000W solar panels would be able to do wonders. So I bought 2 x 100 SP with a 30A Charge Controller. They were simply kept in the storage. Then I bought 2x320W SP, a 3KW Growatt Inverter and EGC 5.12 KH...

I have a Growatt SPF 3000K LVM-ES, a EG4 -48V100AH battery and 1.92KW solar panels for a years now. I have been using the power to run my freezer, refrigerator, lights and garage opener in my garage. As the weather was getting hot, I also run 1200 BTU Midea Window AC when the SOC is more than...

Good answer! I would go for Tier 1, save some troubles. Thanks

What do you mean by Tier 1 , Tier 2 etc? You mean top of the line equipment as Tier1?

Why seal the gaps? They serve as expansion joints!

The way I see is: Imagine in the next few years, everyone is going to install solar panels at their homes and everyone is capable to install their own charging stations at their own homes. Then nobody will go there.

Does any one has this situation? I have a DIY 2.19W system with Growatt inverter and EG-4 battery Off Grid installed at my garage. That basically supports all my electrical need for my garage. My garage also has a 60A sub panel fed from a 200A Main Service Panel and remain as is. I basically...

Were you able to get any IronRidge product elsewhere, I mean cheaper?

I got the same reply when I reached out to them.

Does anyone use Enphase Combiner Box 4 ? I am debating of using which one should I use Combiner Box 3, 3-ES, or 4 and I couldn't figure out the differences but they cost the same. I assumed newer Box 4 is better and I am using Q cells 360W integrated with IQ7+.

Help me understand what comes with: Is the Q cable comes with 2 end terminator with only one wire like the picture shown. One end you plug to the first inverter, the other end you cut the connector off, strip the wire and that goes to the junction box for home run? Why you need to put a...

I don't quite understood you said. Are the existing breakers normal breakers and they are inter-changeable with the breaker I am connecting from PV AC to the Main Service Bus Bar?

I think it serves as a rapid shutdown as anyone can shut it down easily. If you have to shut down from the Main Service Panel, you would need to open the service panel door - the door may got stuck or someone put a lock on it and made that inaccessible. Therefore

Not sure if I understand what a backfed breaker is correctly. Isn't it is just a breaker like one you find in the Main Service Panel that allow current to pass one way through from the grid to load? If I am going to make a Load Side grid-tie connection from my PV AC output to the Service...

I am debating whether I need IQ8 or IQ7+ to go with Qcell 360-365W solar panels. Enpase has IQ7+ already integrated with the SP as part of the SP. That was advertised on their website. I don't know whether they have the option to have IQ8 integrated into it or not.

NO. 250V. Used the number shown on the Unit on the right side . Always used that. Manual usually applies to several models.

I think in term of performance, they are OK. I have their 6x320 W solar panels. They work well. And yes, mine is expensive.

See the latest draft form from IRS on tax rebate https://www.irs.gov/pub/irs-dft/i5695--dft.pdf Used solar equipment including solar panels are not qualified for 30% rebate. If you want claim the rebate without the solar panels, how would you justify you have a solar system installed? IRS may...

Not true. I bought (2 x 320W) Renogy s panels cheaper than Renogy was selling about 6 months ago. Two months ago, I bought 4x320W from Renogy and had to pick them up from their warehouse in California. It was cheaper than I first bought as shipping was not included.

Does anyone has a GW 3K LVM-ES Inverter with an EG4 48V100AH Battery? One early morning I have a battery alarm light on (no beep). I think it is OK (unless it beeps) because when the sun goes up and the battery gets charged and then the alarm light goes off. I was panic and I tried to connect...

I want to ask you this: I have the GW 3K LVM ES and EG4 48V 100AH. I tried to run the BMS test software with my laptop. I referred to Signature Solar youtube video. Signature Solar EG4-Lifepower4 BMS Monitoring Software Walkthrough (Off-Grid Solar Battery LiFePo4) And what I got was No %...

Since you didn't have AC input on your system, your load must have drained the battery. But how could Growatt not shutting in down when the battery hit 46V that I don't understand? If you have AC input and set it to SBU, Grid power would safeguard/support your load when PV and Battery power...

Put that in the sun for couple of hours and then measure the voltage. Should be around 37V for Model 320D. I have 6 of that model.

Question: Did you guy have a AC input connected to your inverter or you just have PV array input? I have the same 3000K ES Inverter with 48V100AH and 6x320W PV array.

3P8S System: 8x37.6=300.8 V and 3x8.26=24.78A; First your inverter must be able to intake 320V (40x8) volts and 30 amps (3x10) on the safe side. The solar panel has already provided the data, so it is unlikely to go 10% higher with respect to the sunlight you are getting- mostly less. In my...

We simply cannot generalize all cases as every case is different. There are many players involve from customer to seller. I am sure seller would have the merchandise well packed and ship out. Then come the shipper who may be a good one on record. Then come the delivery guy who don't care at...

Make sense to use more panels, imaging u sells 3KW @ 0.15/kw and then used their 1 KW @ 0.45/KW. That breaks even.
