4. Configurazione e installazione

Proper installation is critical for safety and performance. If you are unsure about any steps, consult a qualified electrician.

4.1 Disimballaggio e ispezione

• Carefully unpack the inverter and inspect for any shipping damage. Report any damage to your supplier immediately.
• Verificare che tutti i componenti elencati nella lista di imballaggio siano presenti.

4.2 Montaggio

• Mount the inverter on a non-flammable, sturdy surface.
• Ensure sufficient clearance around the inverter for proper ventilation (at least 20 cm on all sides).
• Evitare la luce solare diretta, le fonti di calore e l'umidità.

4.3 Collegamenti di cablaggio

Tutti i cablaggi devono essere conformi ai codici e alle normative elettriche locali.

Figure 4.1: General Connection Diagram. This diagram illustrates how the inverter integrates with solar panels, an MPPT charge controller, battery bank, generator, utility grid, and household appliances.

a. DC Battery Connection:

• Connect the positive (+) terminal of the 48V battery bank to the red (+) terminal on the inverter.
• Connect the negative (-) terminal of the 48V battery bank to the black (-) terminal on the inverter.
• Use appropriate gauge cables for the current draw. Ensure connections are tight and secure.
• Install a DC circuit breaker or fuse between the battery bank and the inverter for protection.

b. AC Input Connection (Grid/Generator):

• Connect the 240V AC input source (utility grid or generator) to the AC input terminal block on the inverter.
• Ensure correct wiring for HOT1 and HOT2. This inverter requires a 240V AC input for its charging function and bypass.
• Install an AC circuit breaker for the input line.

c. AC Output Connection (Loads):

• Connect your 120V/240V AC loads to the AC output sockets or terminal block.
• The inverter provides split-phase output, allowing for both 120V and 240V loads.
• Ensure the total load does not exceed the inverter's capacity.

d. Grounding:

• Connect the inverter's ground terminal to a reliable earth ground. This is a critical safety step.

4.4 Accensione iniziale

• Controllare attentamente tutti i collegamenti elettrici per verificarne la correttezza e la tenuta.
• Ensure all circuit breakers are in the OFF position.
• First, turn ON the DC circuit breaker from the battery bank.
• Then, press the ON/OFF button on the inverter's front panel. The LCD display should illuminate.
• If using AC input, turn ON the AC input circuit breaker.
• Finally, turn ON the AC output circuit breakers to power your loads.

5. Modalità operative

The inverter offers five distinct operating modes to suit various power management needs. These modes can be configured via the front panel controls.

1. AC/Line Priority Mode: In this mode, the inverter prioritizes AC input (utility or generator) to power the load and simultaneously charges the battery bank. If the AC input fails, the inverter automatically switches to battery power.
2. Modalità priorità batteria: The inverter primarily uses battery power to supply the load. When the battery voltage drops below a set threshold, it switches to AC input (if available) to power the load and charge the batteries. Once batteries are sufficiently charged, it reverts to battery power. This mode includes low voltage restore and protect settings.
3. Modalità ecologica: This energy-saving mode puts the inverter into a low-power standby state when the load is less than 10% of its capacity. When the load increases above 10%, the inverter automatically activates and resumes normal operation.
4. Generator Mode: Designed for use with unstable generator AC input. The inverter regulates the incoming 240V AC from the generator, matches it to 60Hz, and provides a stable output voltage all'interno del normale intervallo operativo.
5. Modalità non presidiata: Similar to Battery Priority, but with automatic recovery. When battery voltage is low, the inverter enters standby. It automatically restores normal inverter output once the battery voltage recovers (e.g., from solar charging), enabling fully automatic operation without manual intervention. This mode also features low voltage restore and protect settings.

6. Impostazioni della batteria

The inverter allows for customization of battery parameters to optimize charging and discharge cycles for different battery chemistries.

6.1 Selezione del tipo di batteria

The inverter supports various 48V battery types. Select the appropriate type via the control panel to ensure correct charging voltages and protection thresholds.

Figure 6.1: Supported Battery Types. The inverter is compatible with SLD (Sealed Lead-Acid), GEL, FLD (Flooded), AGM, and LI (Lithium) batteries, with a customizable USER setting.

• Pre-set Options: SLA, AGM, GEL, Li-ion, Flooded.
• Customize Option: For specific battery chemistries like LiFePO4, you can use the 'Customize' setting to manually input charge voltage and other parameters. Refer to your battery manufacturer's specifications for recommended values.

6.2 Corrente di carica regolabile

The maximum AC charging current can be adjusted from 0A to 35A. This allows you to match the charging rate to your battery bank's capacity and manufacturer recommendations.

• Intervallo di impostazione: 0A - 35A.
• Disable Charging: Setting the current to 0A will disable the AC charging function.

7. Manutenzione

Una manutenzione regolare garantisce la longevità e il funzionamento affidabile del vostro inverter.

• Pulizia: Pulire periodicamente l'esterno dell'inverter e assicurarsi che le aperture di ventilazione siano libere da polvere e detriti. Utilizzare un panno asciutto; non utilizzare detergenti liquidi.
• Verifiche della connessione: Annually inspect all electrical connections (DC and AC) for tightness and corrosion. Loose connections can cause overheating and damage.
• Ispezione della batteria: For lead-acid batteries, check electrolyte levels and terminal corrosion as per battery manufacturer guidelines.
• Controllo ambientale: Ensure the installation environment remains within specified temperature and humidity limits.
