Hello, I am curious I inquired about how AFORE inverters 3phase zero export logic work and they said that: If the load on each leg of the inverter is unbalanced it will only produce power equal to the smallest leg for all of its leg for example: L1 - 2kW L2 - 7kW L3 - 8kW The inverter would...

Hello, I recently came across cheap Trina Bi-facial N-type Panels only about 5% more expensive than another Non-bifacial Trina 580 N-type panel. I have read that Bi-facial panels produce more energy than their non bifacial counterpart assuming that there is ample area/light that is being bounced...

Hello been using Deye for quite a while and it would be a first time that i got a battery pack that can supposedly communicate to the inverter, I thought it would be pretty straight forward but it would seem not hence i did not ask the seller on how. Anyway it will be next week until i can go...

I have a deye inverter, in its manual there is something i find confusing PV Input Voltage: 370 (125V- 500V) PV Array MPPT Voltage Range: 150 - 425V No. of MPPT Trackers3 No. of Strings MPP Tracker: 2+2+2 Whats the difference between PV Input Voltage and PV Array MPPT Voltage Range? In my...

Hello friends, this is my first time installing a very large power inverter for my farm, and this is my first time encountering this issue. Usually you would have somebody else do this but since i have experience installing solar systems ( only lower capacity ones though <16KW) I thought to...

My Deye inverter is charging my battery from the grid, even though i set it to not do so. I would like it to stop. Im not sure what setting i am missing here. Anyone has an idea why is it charging? The Battery is connected via CAN bus ,

I have a problem i have 2 18kW deye inverters that are in parallel configuration wiring are all according to the manual. So lets call Inverter 1 as master and inverter 2 as the slave. each inverter has a 16kW worth of panels attached to them in a 3 string configuration (1 string per mppt per...

Planning to build a 16S1P battery, And it would seem that in my area there are 2 popular BMS brands DALLY and 100BALANCE does anyone have experience on these brand if either of them are okay? they both have offerings to what i need, a simple 100A BMS with an included active balancer, and...

Hello friends ! I would like to make my own lifepo4 battery for my solar setup, Im pretty confident i have the technical knowledge to do so, but im in a bit of a delema. I am looking for a container for batterries. I have not chosen a specific battery yet as this would most likely depend on the...

Planning on making my own 16S1P lifepo4 battery packs soon, and would like some advice on where to get the batteries. Well i know where to get them (alibaba) but i do not know which brand are best quality ones. Is there already a consensus on this forum for which battery cells/battery brands are...

I find it odd that it is almost impossible to find Solar or high voltage DC breakers from the reputable brands like schneider,ABB, etc. But there are a lot of these from chinese brands, my problem with these chinese brands is i dont know which of them is reputable. May i know what brand of...

On a hybrid setup, where do you usually place the RCD protection device? I would assume in the load-side, but doesnt that mean that if someone is touching the inverter and got grounded the RCD wont trip. A solution to that would be to also place one in the GRID side of the Inverter, but placing...

I installed a solar system for a client and i have given them access to the app. They do not like how that the battery SOC is represented as voltage, i had always done it this way because it gives me full control of the batteries. But my client does not like this, understandably so as they are...

Hello ! I have a 16kW Deye inverter with 2 battery pack 300Ah batteries. When i tried to communicate with the battery individually there was no problem, the inverter is able to see the battery as indicated "Pylon" and the BMS specifications are also there. My question is how do i connect with...

Assuming i have 200 Panels @ 49V each and i have 10 MPPTs with a 600V nominal 1000V max what would be the most ideal distribution of panels to the MPPT ? Assuming the setup listed below are within the amps rating of each mppt. What i want to know is which of these produces me more power per...

A question for those industrial installer / or installers who have installed a lot of solar panels of roofs, What sealant do you use to cover the base of the footings for your rails to prevent water leaking. More specifically on painted galvanized sheet roofing. I want to hear what do you think...

Hello I was commissioned to install a 30k system to a location with no net metering support, nonetheless the customer wants to install a solar system, i have sized the system so that the solar will not have enough power to export. With that said, i still have to disable export to grid of the...

In the battery page of deye inverters there is there is a setting called BattResistance, Correct me if im wrong but google says this settings is to accomodate for voltage drop of the cables from the inverter to the batteries during charging? How do you find the correct value? So do i just...

I have a battery pack that i think its on the end of its life, it is a 15S pack, and the battery voltage on some of the battery are all over the place. So i was thinking of adding a balancer to help gain a bit of its capacity back. i should be getting the 15S balancer for this pack, But...

I have a 16kW inverter with 2 Battery packs in parallel, the batteries are in battery % mode (inverter sees the battery). But for some reason the battery SOC does not go bellow 15% even if i tell it to drop below that, (at 5 AM it should go to 5% SOC) Anyone has this problem?

What do you call these lever blockers for MCBs I need them to idiot proof transfer switches. I typically see a whole breaker enclosure with this built into them but they are for MCCB. I could find where to get these or even whats the proper term for these

I suspect something is wrong with the MPPT of my inverter. I noticed in the past few days that the inverter is reading out that its only recieving 60W from the panels (keeps moving around from 30-60W). So i went up to roof to check, I have 7 string 350W panels, and during the time i was testing...

I am wondering which orientation of the aluminum railings gives the stronger result should i go along with the Purlins (Red Line) of the roof or across multiple purlins (Green Line) ?

All my load are connected to the UPS port of a deye inverter, In the inverter the Load Consumption is correct but in the Deye Cloud app the reading is wrong (only in the UPS reading), suspiciously it is wrong by 1 decimal here is a sample image: Notice how the inverter is drawing 2.54 kW...

I am installing a 6kW Hybrid System with 5.5kW worth of panels on a small home, And in order to achieve the 5.5kW panel i might have to connect panels that are not on the same angle but generally facing the same direction. Take a look on this Image: Roof orientation is on the upper left: My...
