I visited my brother in law in the big city (Manila); he lives in a mix Industrial, Commercial and Residential neighborhood were 3Phase Y or Delta (3 Transformers) coexists with 3Phase High Leg (2 Transformers). I traced the posts and wires and both groups of transformers share the same High...

This Morning, my Deye shutdown (due to low battery) and I went to investigate the cause. My Deye is configured with Shutdown Voltage of 49.5V or an average cell voltage of 3.010V. My 16s JK is configured UVP of 2.800V and far lower than the 3.01V. However, it is possible one of the cells went...

How much current to cause a significant Ground Fault ? What is the best way to simulate one (on the PV wires, AC wires, Batteries)? (ie to cause an actual Ground Fault on a Deye Inverter for instance) And what equipment best suited to detect them? I want to train people on how to detect ground...

Latest Deye Firmware update added new stuffs that are not in the manual. Would appreciate if you could share the updated manual. Thanks!

Hi, I am sick of having to configure my Deye on site. Is it possible through APP to configure Deye remotely? I heard higher ups can view our config and such.

Assume: Grid's Neutral is bonded to a Grounding Rod in the Main AC Disconnect My electric gears are grounded (chassis are connected to a grounding wire to the grounding rod) The neighborhood receives (High Leg) 3 Phase power from these two transformers. I assume the Right Transformer as 208V...

I live in the tropics, will you recommend going Wind knowing full well it is mostly long sunny days all year round? Likewise Wind Turbines costs x5 more. I could not jog my brain to think viability.

When I started, I do not have the equipment for top balancing, nor for capacity testing. So my 32 cells were never Top Balanced nor matched. I merely assembled the cells and BMS together and plugged them to a Deye Inverter. And because I did not have enough solar panels, my 2 Batteries was...

I have been using 16 pcs of this panel that came with an Solar Air conditioner. I installed these as 8 pcs per string, 2 strings, all facing 170⁰ Azimuth (South), ~15⁰ Tilt (which is optimum for my area). I used that on my Growatt Grid Tie and later (June 2022) Deye 5KW Hybrid. For the longest...

I recently bought Half-Cell Panels. At first glance, I thought it was a great innovation dividing the panel into half-half cells and routing them accordingly. Now it appears I have two pieces of panels in parallel (trace the red line). If the Blue Area (bottom right) of the panel is shaded...

With all this energy crisis world-wide, is EU in particular investing in Solar for the coming winter? How effective is Solar during winter? How much power to PV deliver in winter vs summer? Assume PV are tilted optimally for either case.

I heard lots of kudos for Batrium. I do not really know why. What makes it a great BMS or balancer compared to others? Does it have BMS communication with Inverters/SCC? Does it have high current balancing capability? What kind of balancing does it use? Does it dissipate excess as heat or does...

These three inverters share a common feature called Time Of Use wherein user can limit the amount of Power delivered, between specific time and upto how much battery SOC/Voltage left. Assume I have these settings: What will happen if I have a Grid Power Outage and by 04:50 Battery Voltage...

Certain areas in Philippines are having bad electric services with fluctuating voltages on hourly basis. At first I suggested using Deye; I thought Deye's Grid is completely disconnected from LOAD. I found out this is not the case. The Internal Relays connect GRID to LOAD under normal use. And...

This is the 3P power provided by the Utility Company to a certain neighborhood in Manila, Philippines. L1-L2 = 240V L2-L3 = 240V L3-L1 = 240V NOTE: L3 to N is 208V, But L1 to N is 120V, L2 to N is also 120V Some houses receive 3 wires, either L1L2N or L2L3N or L3L1N. My apartment compound has...

I was about to add ATS to my my Deye installation, but was informed that Deye comes with a built-in ATS! Now what? How should I wire my Deye install now? I;d like to have my whole Home Loads powered even during GRID power outage. How is that gonna work with this new info about Deye having...

I am looking for that thread wherein someone documented his Deye installation project, complete with breakdown/teardown of his unit and such. Does anyone know where I can find that thread? Thanks!

After a few weeks gathering material, I am ready to install additional panels. So before that, I did a mock setup, to see if I will have any issues. I plan to tilt my panels 15⁰, thus one rail is higher than the other. My basic rail is something like this: A hefty ~6" footing with 2 holes for...

I understand how MPPT works; it tracks input V vs input I and come out with the best V*I for optimum Power. Here is my question: Assume my Deye Inverter has dual MPPT ports, each port has Vmp 450V, Imp 13A. Assume I have two identical PV strings. And I had observed that at max power, Voc~...

A few days ago, I got a jolt when I tried attaching a Temperature Probe onto the heatsink. I realized the case GND connection corroded resulting in ~40VAC case/heatsink to floor/wall. So I want to redo case grounding. Q1: For this Deye's case grounding purpose, can I use a solid #14 wire? Or...

I received my 2 JK BMSes early May 2022. And on 15 May, I tried powering up one of them, to test if they are working. Manuf. Date is permanently etched with 2022-05-15 as shown above. Highlighted in in Yellow is the run time of this BMS. It shows >18D17H. Now let us take a look at the logs...

I wonder if this is normal.

I am waiting for Sodium batteries. But may not be cheap at release. However, if manufacturing process is same with LiFePo4, price will go down fast. How about you?

RED Line = Railing Black Rectangle = Solar Panel Assume panel dimension 1m x 2m What is the best way to orient panels for optimal mounting strength? a) horizontally (top) b) vertically (bottom) I am biased towards the vertical orientation. It would use less railings thus cost less. Likewise the...

I am not comparing Solar vs Wind. It is almost typhoon season here in Philippines. 100kph is meh. At least we get 150kph twice a year. A $200 25kg panel can easily do $10,000 damage or worse kill someone when sent flying. So I want to protect my panels against strong wind so I came across this...

Last week I phone my supplier for 7 more 465W Jinko Panels. This Monday, supplier informed me they ran out of railings and later on the 465W Jinko panels are out of stock as well. I scour for other suppliers and found: Trina LongI In your opinion, which of these would you buy? I personally...

So here I heard some inverters that are "low frequency toroidal inverters". 1. What are they? Example? 2. What is their advantage vs regular high frequency inverters? 3. Can toroidal inverters be high frequency? 4. And how do they synthesize sine wave?

A local power company is offering a Peak Off-Peak power rate. Accordingly we can save as much as 35% in bills. One building I administer consumes ~7,500 KWH monthly for common lights, AC, water pump, elevator. I suggested to junk our 30-year-old generator and replace it with Inverter Generator...

Assume I arranged my 16S battery like this: And I like to add a Fuse as shown above for the following reason: 1. The Fuse measures 50mm hole to hole and fits exactly on that spot 2. Less connection: If I use a regular bussbar on that spot, I still need to hook up the fuse elsewhere and have...

I have 1 spare MPPT input and would like to add a string of Panels best suited for the inverter's MPPT specs shown below: Here are my two Panel options: Either I get 6 pcs of 545W panels, Or get 7 pcs of the 465W panels. Which in your opinion best suited for Deye and why? I appreciate your...

My firmware was recently updated and now I see new stuffs under Advanced Function. No idea what these are for. Checkbox ATS function was added too. Deye 5KW Hybrid HMI: 0000-C358

Assume I already have 16 panels but needed more solar power. A 12 Panel solar tracker would cost me about $3500. I can extend this to support my 16 panels. A set of 8 more panels + railings would cost me $1300. Financially, it makes more sense to buy more panels to augment my existing ones...

This caught my attention on my Deye 5K inverter. (Deye 5KW has 2 String Inputs, each with its own MPPT) I have always thought that I could feed 3.5KW~5KW of PV power into a single string. In particular, I plan on oversizing my Solar Panels, to compensate for cloudy skies, to compensate for...

I started solar when we installed a solar AC system. Not soon later, we realized we'd get better result if we go Grid Tie then Hybrid. I currently have a 5KW Deye and 580AH 16S battery bank along with 16 lousy Poly panels giving me 2KW~3.3KW 10AM~2PM on a good sunny day. These panels are...

I could not make out what this "Abnormal current sensor" issue is all about. Any idea? It comes and goes and I have no idea what is happening. Thanks Dan
