If the technical possibilities of the Abiola Turbo Charger are fully exploited, the risk that the resulting output currents exceed the permissible values also increases. This, in turn, could cause a considerable damage to the system. It could even lead to its destruction. For this reason, Abiola offers pluggable measuring devices that display more than just currents. These measuring instruments not only help to comply with the permissible values, but they also help to achieve optimum results.

Abiola offers two measuring instruments, which are basically the same, but are equipped with different cables. The Abiola measuring device displays the following:
* Electricity (A)
* Tension (V)
* Power (W)
* Electrical work (kWh)

Abiola Measuring Device Input (18V)
The measuring instrument is shown in green in the sketch above. It could basically measure the input current for the Turbo Charger. However, this is not so important, as even with a solar power of 120 W, the permissible input current is hardly exceeded.
Much more important is the monitoring of the actual solar output achieved.

Here is a brief example:
In a test, 32 power banks were charged on a sunny day. According to the LED, the built-in battery was charged on the front. Two solar modules were used, i.e. 120 W. The power consumption of all Powerbanks was determined by means of a measuring device. This was about 70 W. One could have assumed that the connected 120 W could easily cope with this. But then the power delivered from the PV module to the Turbo Charger was measured and it was only 35W. It was clear that this would not work for long, as the 32 power banks were only powered at the expense of the built-in battery. Without changing anything, the built-in battery would soon be empty and then the system would have switched off.
The two solar modules were then properly aligned with the sun. Now the measuring device showed an input power of 85W. That’s enough power to charge all 32 power banks and the built-in the battery.

Important:
1. The solar modules must be aligned regularly if the Turbo Charger is used intensively.
2. If you want a full built-in battery in the evening, you should be able to judge during the day if there is enough solar energy available.
Conclusion: The measuring device is used to achieve optimal yields.

Abiola Measuring Device Output (11,1V)
These measuring instruments are shown in yellow in the sketch and have mainly the task to monitor the permissible currents of the ports of the Abiola Turbo Charger. In the article 3 USB splitter, it has already been shown which output currents are permissible.
Normally, these measuring devices are not needed, provided that few ordinary consumers are connected. The Abiola dealer is happy to advise on this.
However, if you use many consumers and consumers with unknown flows, this control makes sense. For example, 6 different phones can exceed the permitted streams. There is better control.

Even if several power meters have been shown in the picture (yellow), this is not necessary in practice, as the measuring devices can be plugged in per port.

An experienced caregiver of an Abiola Turbo Charger soon knows his “sheep”. So he knows exactly how much power is flowing when connecting 6 power banks and which phones are more critical to look at.
Conclusion: The measuring device is used to control the permissible currents.
