Victron Bluesolar light PWM solar controller:

Victron’s range of PWM and MPPT charge controllers are both widely used to charge batteries with solar power.

The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.

A PWM controller is not a DC to DC transformer. The PWM controller is a switch which connects the solar panel to the battery. When the switch is closed, the panel and the battery will be at nearly the same voltage. Assuming a discharged battery the initial charge voltage will be around 13 V, and assuming a voltage loss of 0,5 V over the cabling plus controller, the panel will be at Vpwm = 13,5 V.

The voltage will slowly increase with increasing state of charge of the battery. When absorption voltage is reached the PWM controller will start to disconnect and reconnect the panel to prevent overcharge (hence the name: Pulse Width Modulated controller).

Features:

– Load output with low battery voltage disconnect function.

– Lighting control function, one timer only.

– Two digit seven segment display for quick and easy setting of the load output functionality, including timer setting.

– Three stage battery charging (bulk, absorption, float), not programmable.

– Load output protected against over load and short circuit.

– Protected against reverse polarity connection of the solar array and/or battery.

Victron Energy 70A MPPT Solar Charge Controller

A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximizes this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.

By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. For remote installations – even when there is no internet connection or phone signal nearby – you may be able to monitor your MPPT by Bluetooth-pairing with a LoRaWAN (long-range wide area network) device, available optionally.

By adding the SmartSolar Control Display you will be able to check the status of your Charger and battery-storage at a glance. Simply plug it into the face of your MPPT charger to provide you with real-time monitoring and set-up capabilities.

A MultiPlus, plus ESS (Energy Storage System) functionality
The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external
currentsensor option which extends the PowerControl and PowerAssist function to 50A resp. 100A.
The MultiPlus-II is ideally suited for professional marine, yachting, vehicle and land based off-grid applications.
It also has built-in anti-islanding functionality, and an increasingly long list of country approvals for ESS application.
Several system configurations are possible. For more detailed information see the ESS Design and configuration manual.
PowerControl and PowerAssist – Boosting the capacity of the grid or a generator
A maximum grid or generator current can be set. The MultiPlus-II will then take account of other AC loads and use
whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl
function).
PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a
limited period, the MultiPlus-II will compensate insufficient generator, shore or grid power with power from the battery.
When the load reduces, the spare power is used to recharge the battery.
Solar energy: AC power available even during a grid failure
The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is
compatible with both solar charger controllers and grid-tie inverters.
Two AC Outputs
The main output has no break functionality. The MultiPlus-II 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 the input of the MultiPlus-II. Loads that should not discharge the
battery, like a water heater for example, can be connected to this output.
Virtually unlimited power thanks to parallel and three phase operation
Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/5000/70 units, for example, will provide
25 kW / 30 kVA output power with 420 Amps charging capacity.
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 75 kW / 90 kVA inverter and more than 1200 Amps charging
capacity.
On-site system configuring, monitoring and control
Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface
needed).
Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer,
Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel.
Remote configuring and monitoring
Install a Color Control GX or other GX product to connect to the internet.
Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
When connected to the internet, systems can be accessed remotely, and settings can be changed.
