4. Nastavení a instalace
Správná instalace je zásadní pro bezpečný a efektivní provoz vašeho solárního regulátoru nabíjení. Pečlivě dodržujte tyto kroky.
4.1 Bezpečnostní opatření
- Ensure all connections are tight to avoid loose connections that can cause excessive heat.
- Regulátor instalujte v dobře větraném prostoru, mimo dosah přímého slunečního záření a vlhkosti.
- Vždy nejdříve připojte baterii, poté solární panel a nakonec zátěž. Odpojení proveďte v opačném pořadí.
- Používejte vodiče vhodné pro proud vašeho systému, abyste zabránili přehřátí.
- Ujistěte se, že objem baterietage matches the controller's supported voltage (12V/24V).
4.2 Schéma zapojení a postup připojení
Image 4.1: This diagram illustrates the correct wiring sequence for the PowMr L80 Solar Charge Controller. It shows solar panels connected to the controller's solar input, the controller connected to a 12Vdc or 24Vdc battery, and the controller's load output connected to DC loads. An inverter can be connected to the battery for AC loads.
- Připojte baterii: Connect the positive and negative terminals of your battery to the corresponding battery terminals on the controller. The controller will automatically detect the system voltage (12V nebo 24V).
- Připojte solární panel: Connect the positive and negative terminals of your solar panel array to the corresponding solar panel terminals on the controller. Ensure correct polarity.
- Připojení stejnosměrné zátěže: Connect your DC loads (e.g., LED lights, fans) to the corresponding load terminals on the controller. Ensure correct polarity.
- Connect Temperature Sensor (Optional but Recommended): If using an external temperature sensor, plug it into the designated port for accurate battery temperature compensation.
Důležité: Vždy nejprve připojte baterii, aby ovladač mohl rozpoznat objem systémutage. Connecting the solar panel or load first may damage the controller.
5. Návod k obsluze
Once installed, the controller will begin operating automatically. The LCD display provides various screens to monitor your system and adjust settings.
5.1 LCD displej Overview
The LCD displays real-time information such as solar panel voltage (PV), battery voltage (BATT), load current (LOAD), battery state of charge, temperature, and various charging/discharging parameters. Use the Setup button to cycle through different display screens.
5.2 Funkce tlačítek
- Tlačítko nastavení: Short press to cycle through display screens. Long press (5 seconds) to enter parameter setting mode.
- Tlačítko plus (+): In setting mode, increases the selected value. In display mode, may show additional information or switch modes depending on the screen.
