Solar Systems recommendation that energy saving principles are put into practice and taken into consideration before such a system is purchased i.e. low wattage lighting, gas stove/geyser etc. 5kVA 9-12kWh per day off-grid solar system overview: Solar Module Array This solar system includes a solar module (PV solar panels) array which will generate an average solar yield input of 12kWh/day using a 2250Watt solar module array calculated in George, South Africa. Our solar modules have a 10-year manufacturer’s product guarantee and a terrestrial 25 year an average of 80% solar yield.

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

Battery Storage Capacity The solar system includes an array of 1380Amp 10-15 year Lifespan, 2V Millennium Deep Cycle Batteries with interconnecting cables. These batteries will have the capacity in storage at 18kWh’s usage per day, to cycle your system at 27%, thus maintaining system efficiency and battery lifespan. Please note that actual cycle ratios may vary from installation to installation depending on system use.

During daylight hour’s an off-grid solar system runs off PV as Primary, Battery as secondary.

BMV-700 Precision Battery Monitoring Includes a BMV-700 Precision Battery Monitor: The essential function of a battery monitor is to calculate ampere-hours consumed and the state of charge of a battery. Ampere-hours consumed is calculated by integrating the current flowing in or out of the battery. In case of a constant current, this integration is equivalent to current multiplied by time. A discharge current of 10A for 2 hours, for example, amounts to 20Ah consumed. All Specialized Solar Systems battery monitors use a powerful microprocessor and are expertly programmed with the algorithms needed for precision monitoring.

Standard information and alarms       

Battery voltage (V). Battery charge/discharge current (A). Ampere-hours consumed (Ah). State of charge (%). Time to go at the current rate of discharge. Visual and audible alarm: over- and under voltage, and/or battery discharged. Programmable alarm or generator start relay.

Solar Charge Controller – MPPT (Maximum Power Point Tracking)

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 powervoltage 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

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 a 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).

Victron Blue Power Color Control GX The Color Control provides intuitive control and monitoring for all products connected to it. The list of Victron products that can be connected is endless: Inverters, Multi’s, Quattro’s, all our latest MPPTs, BMV-600, BMV-700, Lynx Ion and even more.

VRM Online Portal Besides monitoring and controlling products on the Color Control GX, the information is also forwarded to our free remote monitoring website: the VRM Online Portal. To get an impression of the VRM Online Portal, visit https://vrm.victronenergy.com/, and try our demo. See also the kWh dashboard screenshot further down in this datasheet.

Future functionality The Color Control has endless possibilities. To implement all our ideas and wishes will take years. There are therefore many features that are not yet available. Functions marked with ‘Future function’ will become available later on, as a firmware update. Firmware updates are free of charge, as with all Victron products. Updating the product is easy: the Color Control GX will update itself automatically, as long as it is connected to the internet. Manual updates can be done with a USB stick and micro SD cards.

Generally, off-grid solar system sizing or specifications are based on your daily wattage usage and peak Wh requirement. Daily watt-hour usage can normally be calculated from your utility bill over a timeperiod but may require more accurate usage pattern monitoring with energy metering data loggers.
