The Magneto 5.12kWh battery range is available in a wall-mount and a rack-mount unit. Both units can be mounted either in rackmount or wall-mount configuration (rackmount unit by means of a wall-mount bracket). The size of the battery is impressive, being much smaller and more compact compared to other batteries with similar specifications.
Communication
The battery does not come with any user manual, which makes inverter communication setup difficult if the CAN or RS485 pin layout is unknown. By testing the most used CAN pin layouts, the CAN pin layout was confirmed to be the Pylontech protocol CAN2.0 used in brands such as Sunsynk, Pylontech, Hubble, REVOV, and many others.
CAN Pin Layout: Pin 2 - GND, Pin 4 - CAN H, Pin 5 - CAN L
Communication between Luxpower and Sunsynk inverters were tested to be stable without any frames dropped.
Parallel communication between multiple batteries can be established by means of the RS485 ports and by setting the 4-bit DIP switch (with address 1 as the master) up to a maximum of 16 batteries.
Performance
The battery can comfortably charge and discharge at 1C without heating up significantly. In our tests, we tested up to 2C with temperatures remaining within their limits without throttling occurring.  It is, however, recommended to stay within the manufacturer's limit of 1C. A great addition to the battery is a physical circuit breaker.
Self-Discharge
The battery's self-discharge is very good, with only 16mAh measured per hour.
Start of Charge
The goal of the charging test is to see how the cell temperature increases with the maximum allowed charge, and if the charging performance is throttled. The battery was charged at 1C for an hour, with cell temperatures T1-T4 at 26°C.

End of Charge
After charging from 0 to 100% SOC for an hour, the temperatures of T1-T4 increased to 44°C (1°C below the specification of 45°C). There was no charging performance throttling, with overall good constant charging curves.

BMS Reading Accuracy
To test the accuracy of the voltmeter reading at the battery terminals as well as any volt-drop resulting of high-resistance busbar usage or leakage of voltage caused by faulty breakers, a multimeter was used to test both the open-circuit and closed-circuit voltage. The measurements show a 99.94% accuracy with an open-circuit voltage of 0.003V, which is negligible.


 User Interface
The battery user interface is a good addition to assist with monitoring the status of the battery. Information such as the pack voltage, current, state of charge (SOC), individual cell voltages, individual temperature sensors, and battery management system (BMS) are shown. Although most new inverters can show battery BMS information via CAN or RS485 communication, the information is mostly limited to pack voltage, pack temperature, SOC and BMS alarm codes. For inverters that are incompatible or not able to display general battery information, or for much better fault-finding and battery monitoring, this display offers a huge advantage. Problems such as cell imbalances, temperature runaway of a specific sensor and detailed BMS fault codes offers both users and installers an advantage in fault-finding without having to send the battery to the manufacturer.

Conclusion
We were really impressed by the compact size of the magneto battery range, good user interface, high performance, and good warranty. The battery offers good scalability with a parallel capacity of up to 16 units. With the price (at the time of writing) for the 5.12kWh rack-mount battery starting at R21 896.00, the Magneto battery range offers excellent value.

Vital to being able to keep within the inverter output limits (and avoid importing expensive grid power unnecessarily) is having the means to display the relevant information in an immediate and accessible way.
That's what I told my wife, anyway.  Really, I'd just scored a bunch of old RC servos on ebay for £5 and I wanted to play with them. 😉

 
In context:

 
It uses 6 servos, a Wemos d1 mini clone and a tri-colour LED.  Dial faces are 3D printed, with a filament change from white to black (which turned out much better than I imagined, TBH).
The servos only had around 90° of sweep angle, so I 3D printed some little holder/gearbox things to get over 180° and provide a shaft for the needle to go on, plus some 'steampunk' needles.


 
All run buy the obligatory D1 mini and held together using the very latest in 'twist and tape' technology.

 
Yee-haw! 🤠
It gets fed the data from 'node-red' running on a Victron CerboGX via UDP packets over WiFi, updating as often as the data changes (approx 3 second intervals).  The LED changes colour according to state, so 'All OK' is green, 'You're getting very close to/exceeding the inverter output limit, so if you don't want to pay for grid, don't turn anything else on' is red, then blue for 'dumping power into the hot water tank'.
It's by no means silent in operation.  I originally made a single-servo version for just PV generation and coded it so that the meter movements were gradual (a kind of PID to get from one value to the next), but apparently it 'sounded like we have cockroaches' when it made it's ticky-scratchy transitions between values, so the big version just jumps between values with a 'zzziiiiiup!' sound.
It's actually quite reassuring to have an audible indication when the sun comes out for 5 seconds, or it starts charging at night.
I'd also put a little radar sensor in there, with the aim of having it detect when there was nobody around, so it could stop displaying to save power/noise.  Unfortunately, that meant that every time you entered the room, all 6 needles would suddenly move at the same time, making you jump out of your skin and spill your horlicks, so we just leave it 'on' all the time now.
There's also a basic web UI, so you can see the same data on your phone or whatever, plus it's useful for troubleshooting:

 
I had fun and learned loads making it - and now it's become a family game to try to cook dinner without making the red light come on. 🙂
 
Libraries used are 'ESPUI' and 'servo', plus 'arduinoOTA'.  Code, FreeCad file for the gearbox & stl file for the arrow-head needle are all in the attached zip.
