3. General Description
The Multi RS Solar is a combined inverter/charger and MPPT solar charger.
It is designed to operate with a 48V battery bank and produces a pure AC sine wave at 230V.
3.1. Two AC outputs
Besides the usual uninterruptible output (AC-out-1), an auxiliary output (AC-out-2) is available that disconnects its load in the
event of battery-only operation. Example: an electric boiler that is allowed to operate only if the genset is running or shore power
is available. There are several applications for AC-out-2.
3.2. PowerControl - maximum use of limited AC power
The product can supply a huge charging current. This implies heavy loading of the AC mains or generator. Therefore a maximum
current can be set. The product then takes other power users into account, and only uses 'surplus' current for charging purposes.
3.3. PowerAssist - Extended use of generator or shore current
This feature takes the principle of PowerControl to a further dimension allowing the product to supplement the capacity of the
alternative source. Where peak power is often required only for a limited period, the product will make sure that insufficient AC
mains or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is
used to recharge the battery.
3.4. Programmable
All programmable settings for this product can be changed with either a mobile phone or computer (Windows requires VE.Direct
to USB dongle), using the free VictronConnect software available on the App Store of your device, or
.
3.5. Programmable relay
The product is equipped with a programmable relay. The relay can be programmed for different applications, for example as a
starter relay for a generator.
3.6. Programmable analog/digital input/output ports
The product is equipped with 2 analog/digital input/output ports.
These ports can be used for several purposes. One application is communication with the allow-to-charge and allow-to-discharge
BMS controls of a lithium-ion battery.
See appendix.
3.7. Built-in Battery Monitor
The ideal solution when the product is part of a hybrid system (diesel generator, inverter/chargers, storage battery, and alternative
energy). The built-in battery monitor can be set to start and stop the generator:
• start at a preset % discharge level
• start (with a preset delay) at a preset battery voltage
• start (with a preset delay) at a preset load level
• stop at a preset battery voltage
• stop (with a preset delay) after the bulk charge phase has been completed
• stop (with a preset delay) at a preset load level
3.8. High efficiency
Outstanding inverter/charger efficiency
- Maximum efficiency of 96%. The inverter is short circuit proof and protected against
overheating, whether due to overload or high ambient temperature.
