Php EpSolar Tracer Class
======

Library for communicating with Epsolar/Epever Tracer BN MPPT Solar Charger Controller

Features
-------
This library connects via RS485 port to the widely known Epsolar/Epever Tracer BN Series MPPT solar charger controller (like mine Tracer 2215 BN) allowing users to get data such as Battery Voltage, Load Current, Panel Power and base on the [Tracer protocol] [protocol] (Modbus).
In order to get it to work you just need tu use a cheap USB/RS485 converter and connect one side to your PC/Raspberry USB port and the other to the solar charger's connector.

Class methods and properties
-------
For better understanding take a look at the "Quick start example"

**getInfoData()** , **getRatedData()** , **getRealtimeData()** , **getStatData()** , **getSettingData()** , **getCoilData()** , **getDiscreteData()**
>These functions get the various data from solar charger and put them in their rispective data arrays. The returned value is TRUE if data received or FALSE if not

**$infoData** , **$ratedData** , **$realtimeData** , **$statData** , **$settingData** , **$coilData** , **$dicreteData**
>These arrays are populated after calling the respective function with the data received from solar charger. The data acquired are rispectively: Info Registers, Rated Data Registers, Real-time Data/Status Registers, Statistical Data Registers, Settings Parameter Registers, Coils Registers, Discrete Input Registers. For example $realtimeData[3] could be 12.23 (Volts). These data are updated everytime you call the connected method, i.e. for updating $realtimeData you have to call getRatedData()

**$infoKey** , **$ratedKey** , **$realtimeKey** , **statKey** , **$settingKey** , **$coilKey** , **$discreteKey**
>These fixed arrays contains the "Key" (the label) of the specific data. For example $realtimeKey[3] is "Battery voltage"

**$ratedSym** , **$realtimeSym** , **$statSym** , **$settingSym**
>This fixed array contains the "Symbol" conected to the value. For example $realtimeSym[3] is "V" (Volts)

Quick start example (example_cli.php)
------
This example will print all datas received from solar  charger
```php
<?php
require_once 'PhpEpsolarTracer.php';

$tracer = new PhpEpsolarTracer('/dev/ttyUSB0');

if ($tracer->getInfoData()) {
	print "Info Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->infoData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->infoKey[$i].": ".$tracer->infoData[$i]."\n";
	} else print "Cannot get Info Data\n";

if ($tracer->getRatedData()) {
	print "Rated Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->ratedData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->ratedKey[$i].": ".$tracer->ratedData[$i].$tracer->ratedSym[$i]."\n";
	} else print "Cannot get Rated Data\n";

if ($tracer->getRealtimeData()) {
	print "\nRealTime Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->realtimeData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->realtimeKey[$i].": ".$tracer->realtimeData[$i].$tracer->realtimeSym[$i]."\n";
	} else print "Cannot get RealTime Data\n";

if ($tracer->getStatData()) {
	print "\nStatistical Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->statData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->statKey[$i].": ".$tracer->statData[$i].$tracer->statSym[$i]."\n";
	} else print "Cannot get Statistical Data\n";
	
if ($tracer->getSettingData()) {
	print "\nSettings Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->settingData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->settingKey[$i].": ".$tracer->settingData[$i].$tracer->settingSym[$i]."\n";
	} else print "Cannot get Settings Data\n";

if ($tracer->getCoilData()) {
	print "\nCoils Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->coilData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->coilKey[$i].": ".$tracer->coilData[$i]."\n";
	} else print "Cannot get Coil Data\n";

if ($tracer->getDiscreteData()) {
	print "\nDiscrete Data\n";
	print "----------------------------------\n";
	for ($i = 0; $i < count($tracer->discreteData); $i++)
		print str_pad($i, 2, '0', STR_PAD_LEFT)." ".$tracer->discreteKey[$i].": ".$tracer->discreteData[$i]."\n";
	} else print "Cannot get Discrete Data\n";
?>
```
and will produce the following output on my solar charger:

Note
------
If you use this class in HTTPD and not CLI don't forget to give the user the permssion to use serial port (for example with Apache on Debian: usermod -a -G dialout www-data)
