 Solar Module Array to Supply

To achieve an average energy input solar generation of 24kWh/day with PV solar modules in George, Western Cape South Africa,  Specialized Solar Systems recommends a PV solar module array capacity of 4500Watt, at a fixed tilt angle of 34°.  Specialized Solar Systems PV solar modules have a 10-year manufacturer’s product guarantee and a terrestrial 25 year 80% yield.


Solar yield is determined by your location, PV solar panel orientation, PV solar panel shading, the PV solar panel surface condition, system usage, weather conditions,  and use at a 34° Tilt Angle Facing North with full day exposure to the sun i.e. no shading.

Battery Storage Capacity

900Amp 2V Flooded Lead Acid Cells. Based on primary usage being consumed during the day these units will have the capacity in storage to support 6kWhrs per night and/or when Mains is unavailable to run approximately 16kWhrs before Eskom comes back online again.

Please note that this figure excludes the power being generated and supplied directly to loads from the solar modules during the day when Mains is offline. This will increase the amount of power in reserve when Mains fails.


Solar Charge Controller – MPPT (Maximum Power Point Tracking)

PV voltage up to 150 V

  • The Blue Solar MPPT 150/70 and 150/85 charge controllers will charge a lower nominal-voltage battery from a higher nominal voltage PV array.
  • The controller will automatically adjust to a 12, 24, 36, or 48 V nominal battery voltage.

Ultra-fast Maximum Power Point Tracking (MPPT)

  • Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Advanced Maximum Power Point Detection in case of partial shading conditions

  • If partial shading occurs, two or more maximum power points may be present on the power-voltage curve.
  • Conventional MPPT’s tend to lock to a local MPP, which may not be the optimum MPP.
  • The innovative Blue Solar algorithm will always maximize energy harvest by locking to the optimum MPP.

Outstanding conversion efficiency

  • Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).

Flexible charge algorithm

  • Several preconfigured algorithms.
  • One user programmable algorithm. Manual or automatic equalization. Battery temperature sensor. Battery voltage sense option.

Programmable auxiliary relay

  • For alarm or generator start purposes

Extensive electronic protection

  • Over-temperature protection and power derating when the temperature is high.
  • PV short circuit and PV reverse polarity protection.
  • Reverse current protection.

CAN bus

  • To parallel up to 25 units, to connect to a Color Control panel or to connect to a CAN bus network
  • PV short circuit and PV reverse polarity protection. Reverse current protection.

 Pure Sine Wave Bi-Directional Inverter/Charger

1 x 5000/24/120 Victron Multiplus Inverter/Charger

  • Continuous output power at 25’C (VA) per unit 5000
  • Continuous output power at 25’C (W) per unit   4500
  • Continuous output power at 40’C (W) per unit   4000
  • Peak Power (W) per unit  10 000

 Multi-functional, with intelligent power management

  • The Multiplus is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology, and a high-speed AC transfer switch in a single compact enclosure. Next, to these primary functions, the Multiplus has several advanced features, as outlined below.

 Two AC Outputs

  • The main output has no-break functionality. The Multiplus takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the Multiplus. Loads that should not discharge the battery, like a water heater, for example, can be connected to this output (second output available on models with 50A transfer switch only).

 Virtually unlimited power thanks to parallel operation

  • Up to 6 Multi’s can operate in parallel to achieve higher power output. Six 24/5000/120 units, for example, will provide 25 kW / 30 kVA output power with 720 Amps charging capacity.

 Three phase capability

  • In addition to parallel connection, three units of the same model can be configured for three-phase output. But that’s not all: up to 6 sets of three units can be parallel connected for a huge 75 kW / 90 kVA inverter and more than 2000 Amps charging capacity.

 Power Control – Dealing with a limited generator, shore side or grid power

  • The Multi Plus is a very powerful battery charger. It will, therefore, draw a lot of current from the generator or shore side supply (nearly 10A per 5kVA Multi at 230VAC). With the Multi Control Panel, a maximum generator or shore current can be set. The Multi Plus will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded.

 Power Assist – Boosting the capacity of shore or generator power

  • This feature takes the principle of Power Control to a further dimension. It allows the Multi Plus to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the Multi Plus will make sure that insufficient shore 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.

 Four stage adaptive charger and dual bank battery charging

  • The main output provides a powerful charge to the battery system by means of advanced ‘adaptive charge’ software. The software fine-tunes the three-stage automatic process to suit the condition of the battery and adds a fourth-stage for long periods of float charging. The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on our website, under Technical Information. In addition to this, the Multi Plus will charge the second battery using an independent trickle charge output intended for the main engine or generator starter battery (trickle charge output available on 12V and 24V models only).


The Venus GX

  • Provides intuitive control and monitoring for all Victron power systems. The list of Victron products that can be connected is endless: Inverters, Multis, Quattros, MPPT solar chargers, BMV battery monitors, Lynx Ion with Shunt and more.

VRM Online Portal

  • All readings are forwarded to our free remote monitoring website: the VRM Online Portal.

Remote Console on VRM

  • The way to access the device for setting up, as well as monitoring, is via Remote Console. Either via VRM, via the built-in WiFi Access Point, or on the local LAN/WiFi network.

Automatic Genset start/stop

  • A highly customizable start/stop system. Use state of charge, voltage, load and other parameters. Define a special set of rules for quiet times, and optionally a monthly test run.

The heart of ESS –Energy Storage System

  • The Venus GX is the Energy Manager in an ESS system.

Data logging

  • When connected to the internet, all data is sent to the VRM Portal. When there is no internet connection available, the Venus GX will store the data internally, up to 48 hours. By inserting a micro SD-card or USB stick, more data can be stored. These files can then be uploaded to the VRM Portal, or offline converted with the Victron Connect app, for analysis.
