  • The wiring diagram only shows the key components in a typical DC-coupled off-grid energy storage system for illustrative purposes. The wiring might be different depending on the system configuration. Additional safety devices, including disconnect switches, emergency stops, and rapid shutdown devices, might be required. Wire the system according to the regulations at the installation site.
  • The connection of AC IN ports varies depending on the connected grid systems. For single-phase 120V grid systems, only AC IN L1 and AC IN N ports are used for the input. For split-phase 120V/240V grid systems, AC IN L1, AC IN L2, and AC IN N ports are used for the input.

Preparation

Plan a Mounting Site
The inverter charger requires adequate clearance for installation, wiring, and ventilation. The minimum clearance is provided below. Ventilation is highly recommended if it is mounted in an enclosure. Select a proper mounting site to ensure the inverter charger can be safely connected to the battery and grid/AC generator with the relevant cables.

Renogy REGO 3000W 12V Pure Sine Wave HF Inverter Charger User Manual -6

  • Risk of explosion! Never install the inverter charger in a sealed enclosure with flooded batteries! Do not install the inverter charger in a confined area where battery gases can accumulate.
  • The inverter charger should be installed on a vertical surface protected from direct sunlight.
  • Keep the inverter charger out of the reach of children and animals.
  • Do not expose the inverter charger to flammable or harsh chemicals or vapors.
  • Make sure that the inverter charger is installed in a place at ambient temperature from -4°F to 140°F (-20°C to 60°C).
  • Make sure that the inverter charger is installed in an environment with relative humidity between 0% and 95% and no condensation.
  • If the inverter charger is installed improperly on a boat, it may cause damage to the components of the boat. Has the inverter been charged by a qualified electrician?
  • The inverter charger cannot operate at full load in ambient temperatures above 113°F (45°C).
  • The inverter charger should be as close to the battery as possible to avoid voltage drop due to long cables.
  • It is recommended that all cables (except communication cables) should not exceed 10 meters (32.8 feet) because excessively long cables result in a voltage drop. The communication cables should be shorter than 6 m (19.6 feet).
  • The cable specifications listed in the user manual account for critical, less than 3% voltage drop and may not account for all configurations.
  • Ensure the inverter charger is firmly grounded to a building, vehicle, or earth grounded. Keep the inverter charger away from EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage/interference to the equipment.

To ensure good ventilation and optimal system performance, we recommend mounting the inverter charger vertically (terminals down) on a wall or horizontally on the floor.
