Multi HS19 Solar 15k

	The is a 19" rack mountable unit. It is intended to be installed in a standard 19" rack mounting cabinet. The cabinet should allow unobstructed air flow through the from the front to the back. It's advisable to leave at least a 1U space above and below the unit to aid in cooling. If components within the cabinet are in contact with one another they'll exchange unwanted heat between them. To ensure a trouble free operation of the , it must be used in locations that meet the following requirements: a) Avoid any contact with water. Do not expose the to rain or moisture. b) Install the in a standard 19" cabinet, with a 1U clearance above and below it. c) The must be installed in a non-flammable cabinet and the construction materials surrounding the installation should also be non-flammable. d) Do not place the in direct sunlight. Ambient air temperature should be between 0°C and 60°C (humidity 95% non-condensing). e) Do not install the in an environment where the air could be contaminated with particulate matter such as soot, dust or salt. For example, conductive soot from the exhaust of a diesel generator could be drawn into the encolsure and cause short circuits inside it. f) Do not install the where flammable or corrosive gases or vapours could come near the installation. g) Do not obstruct the airflow through the . The cabinet should allow unobstructed air flow through the from the front to the back. h) If the is installed in an area used for general storage, ensure that no flammable materials such a cardboard boxes are stored close to the installation. Ensure that the end user is aware of these requirements.
	The contains potentially dangerous voltages. It should only be installed under the supervision of a suitable qualified installer with the appropriate training, and subject to local requirements. Please contact Victron Energy for further information or necessary training.
	Excessively high ambient temperature will result in the following: Reduced service life. Reduced charging current. Reduced peak capacity or shutdown of the inverter. Never position the appliance directly above lead-acid batteries.
	For safety purposes, the should be installed in a heat-resistant environment. You should prevent the presence of: e.g. chemicals, synthetic components, curtains or other textiles, etc., in the immediate vicinity.
	Never connect batteries directly to the . Always ensure that adequate circuit protection is installed between the batteries and the .

High DC voltages are supplied to the Multi HS19 Solar when a connected PV array is exposed to light.

PV modules must have an IEC 61730 Class A rating.

Ground the frame of the PV array following local regulations.

All disconnection means for batteries, PV isolators and AC circuit breakers must remain accessible at all times. A circuit breaker rated at 32A or less is required for the AC input.

If local installation regulations require an external Residual Current Device (RCD), a separate type A RCD with rated residual operating current of 300mA or higher may be installed at AC input. When required by local regulations, a type B RCD may also be used, although it is not required by Victron Energy.

This is a safety class I product (supplied with a protective grounding terminal) and is intended to be used in a TN or TT earthing system. Its AC input and/or output terminals and/or grounding point on the product must be provided with an uninterruptible grounding point for safety purposes. In a fixed installation, an uninterruptible grounding can be secured by means of the grounding wire of the AC input. Otherwise the casing must be grounded. Whenever it is likely that the grounding protection has been damaged, the product must be turned off and secured against unintended operation; please contact qualified service staff. The is provided with a ground relay that automatically connects the Neutral output to the chassis if no external AC supply is available. If an external AC supply is provided, the ground relay will open before the input safety relay closes. Follow the local national wiring standards, regulations and installation instructions for electrical work.

Use the VictronConnect App for configuration, control and view the status of the . You can view the current firmware version and preform firmware updates using VictronConnect. Operational status and firmware version is also displayed on the front panel LCD.

The VE.Can port is used for other VE.Can connected products such as an external energy meter or a GX device for remote monitoring and fault indication.

The illustration shows the front and rear panel connectors with a description for each one in the table below.

The is built using Staubli MC4 connectors. There are many other brands available, but some manufacturing variations mean that they may make poor contact and cause excessive heat. There are also inferior brands on the market which will likely cause problems.

There is a maximum short circuit current per tracker. Check the technical specifications section for details.

When the MPPT switches to float stage it reduces battery charge current by increasing the PV Power Point voltage.

The maximum open circuit voltage of the PV array must be less than 600 V when the battery is at float voltage.

In order to utilize the full capacity of the product, batteries with sufficient capacity and battery cables with sufficient cross section should be used. The use of undersized batteries or battery cables will lead to:

The battery connection terminals on the are Amphenol SurLok Plus.

The AC connection terminal blocks can be found on the front panel.

The AC connector block is a push-in spring connector.

Conductor insulation should be stripped to expose 15mm of bare conductor.

Push the conductor into the round hole of the terminal block position. Multi-stranded conductors may require a small screwdriver to be inserted into the square hole to release the spring tension which will ease insertion of the conductor.

Refer to the technical specifications page for information about cable cross sectional area.

AC output 1 will be active when the is running on battery. Both AC outputs will be active when the AC input is available.

The AC input must be protected by a fuse or circuit breaker rated according to the model of , and cable cross-section must be sized accordingly. If the input AC supply is rated at a lower value, the fuse or circuit breaker should be down sized accordingly.

VE.Direct

This can be used to connect a PC/laptop to configure the inverter with a VE.Direct to USB accessory. Can also be used to connect a Victron GlobalLink 520 to allow for remote data monitoring.

VE.Can

Used to connect to a GX Device, and/or daisy-chain communications to other VE.Can compatible products.

Battery Can

Connect to the Canbus port of the battery system.

Bluetooth

Used to connect to the device via VictronConnect for configuration.

Remote on / off connector

The remote on/off connector has two terminals, the “Remote L” and the “Remote H” terminal.

The ships with the remote on/off connector terminals connected to each other via a wire link.

Note that for the remote connector to be operational, the main on/off switch on the Multi needs to be switched to “on”.

The default function of the remote on/off connector is to remotely switch the unit on or off.

Programmable relay

Programmable relay which can be set for general alarm, DC under voltage or genset start/stop function. See the Technical specifications section for contact ratings.

12V input

This input is used to keep the alive and to allow for black start situations.
