Victron Home Battery Storage, 3KVA Inverter, 4.8 kWh Lithium, On-line Monitoring built-in, Works in a Power Cut
This is a Victron home battery storage system that is designed to work with solar panels or just charge from cheap rate electricity overnight.
How it works with a Solar system
When this Victron home battery storage system is set up to work with an existing solar installation, you would wire it into the mains and connect the blue CT clamp around the incoming supply. This CT detects the flow of power in and out of your property when there is excess solar the CT will detect this and allow the battery to charge. However, when there is no solar or little solar and power from the grid passes by the CT this will tell the battery to discharge and cover the load that the grid was supplying, this means that your bill will be reduced and your purchasing of electricity from the grid will be less
How this battery works with cheap rate electricity
If you don't have solar or even if you do have solar you can charge your battery from cheap overnight electricity using a smart meter or Economy7. This means that while you're asleep your battery system can come on automatically and charge from this cheap rate electricity and again turn off automatically, this is normally between 4 & 6 am. This would enable you to run your house on batteries for the remainder of the day depending on your usage.
Power during a powercut or blackout
Built into the Victron inverter charger is a secondary output which can be used in the event of a power cut to provide power from the batteries to keep your house powered with electricity to run things such as fridges freezers boilers and lights
Built into the Victron is a GX device, this GX device will plug into your Internet connexion or connect to Wi-Fi and allow you to monitor and control your system from anywhere in the world. This gx device is controllable from your mobile phone or laptop and allows you to make settings changes and to enable and disable charging schedules. It would also allow Callidus to come onto the system remotely and check that it's working correctly once you have set it up.
The MultiPlus-II 3kva GX
Victrons New 48V Inverter/Charger With GX Inside
An Inverter/Charger with device networking built-in, the MultiPlus-II GX communicates with a solar charger, batteries, and other devices to control a grid-connected, off-grid, or remote power installation. Capable of parallel operation for increased power output, or battery charge-rates, the MultiPlus-II GX can also be configured for three-phase supply. A host of advanced features - such as uninterrupted power supply, setting load limits, and supplementing limited grid-power availability with battery power - can all be controlled straight from your phone or smart device. Remote monitoring is also possible.
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
ESS: Energy Storage Systems
The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters. For examples and more detailed information see the Victron Energy ESS (Energy Storage System) manual.
Uninterrupted AC power (UPS function)
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
Remote Monitoring and Control
Monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, via the required Color Control GX or Venus GX, from adjusting your Multi to auto starting a back generator and more...
