String Monitoring

String Control

ams StringControl was designed to control the function of small and midsize photovoltaic systems.

The integrated analogue meters continuously measure the current flow of all single strings including the connected modules.

ams StringControl is suitable for the integration in new installed phohtovoltaic systems as well as for the retroactive installation.

Contamination, corrosion, marten bite, loose cabling or similar often can cause a reduced power generation, which remain unnoticed.

The monitoring of the strings via ams StringControl is thereby fully uncomplicated. By having a uniformly exposure to sunlight of the modules and fully functional strings the analogue meters indicate an identical current flow via the displayed current value. In case the functionality of one of the strings should be limited, because e.g. one single module or just a single solar cell is damaged, the corresponding analogue meter which is monitoring this string will indicate a lower current value as due to a failure the complete string can't generate best possible power output anymore.

In this case an electrically qualified person has to check modules and strings and to fix the damage that the system again can work efficient and properly.

With ams StringControl you're in the position to monitor the functionality of your photovoltaic system immediatelly and easily at a glance and can react very quickly in case of a reduced power generation.

Types:

ams StringControl 310A with 3 analogue meters for up to 3 string

ams StringControl 410A with 4 analogue meters for up to 4 strings

ams StringControl 610A with 6 analogue meters for up to 6 strings

These measuring meters are designed to operate as edgewise meters in a railway environment. Available sizes are 96 x 48 mm or square-shaped in 72 x 72, 96 x 96 and 144 x 144 mm. Square meters are available with a 90° or 240° movement. 235x150 mm

e.g. 72x72 mm e.g. 72x72 mm

215x110 mm		The EB 220 is an analogue meter with a high-quality moving coil movement. The big open 215 x 110 mm display ensures good readability even from a distance. This meter is frequently used in teaching.
e.g. 72x72 mm		SQ 72 DS load meter with built-in LED
e.g. 72x72x mm		Phase sequence indicators are used to set or monitor the rotary field direction or phase sequence in three-phase current supply networks.
e.g. 72x72 mm		Operating hours counters for AC and DC currents in the sizes 48 x 48, 72 x 72 and 96 x 96 mm. Counter range up to 99 999.99 hours.
