# Ahoy configuration
|
|
|
|
## Prerequists
|
|
You have build your own hardware (or purchased one). The firmware is already loaded on the ESP and the WebUI is accessible from your browser.
|
|
|
|
## Start
|
|
But how do I get my data from the inverter?
|
|
|
|
The following steps are required:
|
|
1. Set the pinning to communicate with the radio module.
|
|
2. Check if Ahoy has a current time
|
|
3. Configure the inverter data (e.g. serialnumber)
|
|
|
|
### 1.) Set the pinning
|
|
Once you are in the web interface, you will find the "System Config" sub-item in the Setup area.
|
|
|
|
This is where you tell the ESP how you connected the radio module.
|
|
Note the schematics you saw earlier. - If you haven't noticed them yet, here's another table of connections.
|
|
|
|
|
|
#### OpenDTU Fusion (ESP32-S3)
|
|
| NRF24 Pin | ESP Pin|
|
|
|---------| --------|
|
|
| CS (4) | GPIO37
|
|
| CE (3)| GPIO38
|
|
| IRQ (8) | GPIO47
|
|
| SCLK (5)| GPIO36
|
|
| MOSI (6)| GPIO35
|
|
| MISO (7)| GPIO48
|
|
|
|
| CMT2300A | Pin |
|
|
|---------| --------|
|
|
| CMT| Enabled |
|
|
| SCLK| GPIO6
|
|
| SDIO| GPIO5
|
|
| CSB| GPIO4
|
|
| FCSB| GPIO21
|
|
| GPIO3| GPIO8
|
|
|
|
### 2.) Set current time (standard: skip this step)
|
|
Ahoy needs a current date and time to talk to the inverter.
|
|
It works without, but it is recommended to include a time. This allows you to analyze information from the inverter in more detail.
|
|
Normally, a date/time should be automatically retrieved from the NTP server. However, it may happen that the firewall of some routers does not allow this.
|
|
In the section "Settings -> NTP Server" you can also get the time from your own computer. Or set up your own NTP server.
|
|
|
|
### 3.) Set inverter data
|
|
|
|
#### add new inverter
|
|
Now it's time to place the inverter. This is necessary because it is not the inverter that speaks first, but the DTU (Ahoy).
|
|
|
|
Each inverter has its own S.Nr. This also serves as an identity for communication between the DTU and the inverter.
|
|
|
|
The S.Nr is a 12-digit number. Check [here (german)](https://github.com/lumapu/ahoy/wiki/Hardware#wie-ist-die-serien-nummer-der-inverter-aufgebaut) for more information.
|
|
|
|
#### set pv-modules (not necessary)
|
|
Click on "Add Inverter" and enter the S.No. and a name. Please keep the name short!
|
|
|
|
|
|
|
|
|
|
In the upper tab "Inputs" you can enter the data of the solar modules. These are only used directly in Ahoy for calculation and have no influence on the inverter.
|
|
|
|
#### set radio parameter (not necessary, only for EU)
|
|
In the next tab "Radio" you can adjust the power and other parameters if necessary. However, these should be left as default (EU only).
|
|
|
|
#### advanced options (not necessary to be changed)
|
|
In the "Advanced" section, you can customize more settings.
|
|
|
|
Save and reboot.
