  • Page 3: Safety Instructions

    SUN Inverter Manual 1. Safety instructions General Please read the documentation supplied with this product first, so that you are familiar with the safety signs and directions before using the product. This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only.

  • Page 4: General Description

    2.2. Solar charge controller The SUN inverter is equipped with a PWM solar regulator. Solar panels can be directly connected to the SUN inverter. Solar power will be used to charge the batteries or help to provide energy to the inverter AC load.

  • Page 5: The Victronconnect App

    SUN Inverter Manual Additional parameters can be monitored via VictronConnect: • Inverter state. • Battery voltage. • AC output voltage. • Percentage of nominal AC load. • Solar power and voltage. • Warning and alarms. For the full list of all LED indications and monitoring parameters see the Operation [20] chapter.

  • Page 6: Temperature Sensor

    2.10. BMS communication The remote connector can be used by a lithium Battery Management System (BMS) to control the SUN Inverter, to stop the inverter when the batteries are too far discharged or to stop the solar charger when the batteries are overcharged or when the battery temperature is below 5°C.

  • Page 7: Installation

    SUN Inverter Manual 3. Installation • This product should be installed by a qualified electrician. • During installation ensure that the remote connector with wire bridge is removed (or switch off the remote on/off switch if installed) to be sure that the inverter cannot be switched on unexpectedly.

    SUN Inverter Manual Mounting type Recommended? IP rating Notes Vertical wall mounting, fan at the IP20 Be aware that potentially small bottom. objects or dust can fall into the inverter through the ventilation openings at the top. Vertical mounting, fan on top.

  • Page 9: Chassis To Ground Connection

    SUN Inverter Manual • The inverter has a floating ground. To ensure proper functioning of a GFCI (or RCCB, RCB or RCD) to be installed in the AC output circuit of the Inverter, an internal or external neutral to ground connection needs to be made.
  • Page 10 REMOTE connector - location H and L terminal. Battery temperature sensor Battery temperature information can be used by the SUN inverter to do the following: • In case of lead-acid batteries, to facilitate temperature compensated charging. The charge voltage is reduced when the batteries are hot and the charge voltage is increased when the batteries are cold.

    SUN Inverter Manual 4. Configuration The inverter is ready for use with the standard factory settings (see the Technical specifications [26] chapter). The inverter can be configured using the VictronConnect app. Connect using a smartphone or tablet via Bluetooth or using a computer via USB and a VE.Direct to USB...

  • Page 13: Dynamic Cut Off

    SUN Inverter Manual 4.3.1. Dynamic cut off The "Dynamic cut off" feature makes the low battery shutdown protection a function of the battery current drawn from the battery in relation to the battery voltage. When a high current is being drawn from the battery, a lower cut off voltage threshold is being used, for example 10V. And similarly, when the battery is only being discharged slowly, a high cut off voltage is used, for example 11.5V.

  • Page 14: Battery Settings

    SUN Inverter Manual VictronConnect app showing the "Dynamic cut off" settings 4.4. Battery settings Max charge current This setting sets the maximum battery charge current. It is by default set to the maximum solar charge current. Use this setting to reduce the charge current, for example, when a smaller battery bank is used that requires a lower charge current.

  • Page 15: Battery Charge Algorithm Settings

    SUN Inverter Manual This setting uses factory pre-defined presets for a large variety of battery types. These pre-defined charge algorithms are suitable for almost all installations. It is possible to also create user-defined battery presets. The chapter Customize battery charge algorithm explains how to do this.
  • Page 16 SUN Inverter Manual Absorption voltage This setting sets the absorption voltage. Adaptive absorption time This setting enables or disables the adaptive absorption time. • When disabled: The length of the absorption stage is the same each day, the length is determined by the "Maximum absorption time"...
  • Page 17 By default, the SUN Inverter uses its internal temperature for battery temperature compensated charging. An internal temperature reading is taken in the morning and then again when the e SUN Inverter has been idle for at least one hour, for example when the charger is not actively charging a battery or supplying a load.

  • Page 18: Ve.smart Network

    SUN Inverter Manual When the SUN Inverter is part of a VE.Smart network and receives a battery temperature reading from a Battery Sense or a battery monitor with a temperature sensor, the actual battery temperature will be used for temperature compensated charging throughout the day.

  • Page 19: Ve.smart Network Setup

    SUN Inverter Manual • Battery voltage sensing - the measured battery voltage is used by the chargers in the network to to compensate the charge voltage should there be a voltage drop over the battery cables. • Current sensing - The measured battery current is used by the charger so it knows the exact tail current at which the absorption stage should end and the float (or equalisation) stage should start.
  • Page 20 SUN Inverter Manual • Open the VictronConnect app. • Select a device that needs to be removed from the VE.Direct network. • Navigate to the settings page by clicking the gear symbol. • Click on "VE.Smart networking". • Click on "leave network".

LED behaviour Operational mode Battery Yellow STATE The solar charger is switched off, or The battery is not being charged by the LED off.

  • Page 26: Monitoring Via Victronconnect

    SUN Inverter Manual The inverter will shut down if it detects a too high DC ripple. The LEDs will signal shutdown due to high DC ripple. The inverter will wait 30 seconds and then resumes operation again. If after 3 restarts, the DC ripple voltage is still too high, the inverter will shutdown and will not attempt to restart again.
