Battery Charger - Victron energy RS Smart Solar 48/6000 Manual

2. DESCRIPTION
Fully configurable
• Low battery voltage alarm trip and reset levels
• Low battery voltage cut-off and restart levels, or Dynamic cut-off
• Output voltage 210 - 245V
• Frequency 50 Hz or 60 Hz
2.1 High efficiency
The overall maximum efficiency of the inverter RS is over 96%.
The inverter is short circuit proof and protected against overheating, whether due to overload or high ambient temperature.
2.2 High voltage MPPT solar controller
Two strings can be connected to the inputs. Both are wired parallel to one tracker, therefore the two strings must be equal in number of
solar panels and type. The total allowed input current is limited by the device to 18A.
! Do not connect PV with a potential current greater than 20A as this could damage the device.
When the MPPT switches to float stage it reduces the battery voltage by increasing PV voltage (reducing the total solar power output).
For this system to work, the maximum open circuit voltage of the PV array must not be higher than 8 times the minimum battery voltage
when at float, to an absolute maximum of 450V. Exceeding these open circuit PV voltage limits is forbidden and will lead to system
shutdowns and damage to the device.

2.3 Frequency shift function
When external PV inverters are connected to the output of the inverter, excess solar energy is used to recharge the batteries, just as
with the internal MPPT solar controller. Once the battery absorption voltage is reached, charge current will reduce by shifting the output
frequency higher. This feature is used for battery over charge protection and solar assist. It does not allow charging the battery to fully
charge to 100% SoC for safety reasons.
2.4 High peak power
The inverter is capable of providing 50Amp AC or 9000W for a short time.

* Remote L functions as 'allow to charge' in case lithium battery is selected and remote H functions as 'allow to discharge'. Use
miniBMS for the inverter RS with Victron lithium batteries.

2.6 Battery charger

The batteries are charged by solar energy using the built-in MPPT solar controller. It can also be charged by a PV grid inverter
connected to the AC out. In this case the battery will be charged to ~98%. The built-in MPPT has a power limit of 4000W. So the
maximum charging current for a 50V battery will be 80A. If an additional PV grid inverter is connected (max 5000W) the maximum total
charging current is limited to 100A. The maximum charging current of 100A is reduced if battery voltage goes above 60V. A custom
maximum charge current value can also be defined by the installer in VictronConnect.
The charger algorithm is the same as for the BlueSolar MPPT solar controllers. This provides built-in battery preset parameters, and
allows for expert mode to define additional charging parameters. Please see the MPPT section of the VictronConnect manual for
additional explanation of these charging features.
