You can’t eectively manage a large PV system if you can only see data
from one generation meter. Systems over 30kW should consider granular
monitoring to provide insight into performance among various hardware
devices and all sections of the array. Granular monitoring requires added
hardware as well as software for each reporting node. Your DECK sales rep
can help you plan a granular monitoring package to t your project needs.
1 BASIC MONITORING: The most basic level of monitoring receives data from just one reporting node, the generation
meter. This level of monitoring is often all that is needed for smaller projects such as residential PV systems. The DECK
core package comes standard with one-node reporting. For commercial systems, inverter monitoring is typically added
to provide insight into inverter performance through the web interface.
3 STRING MONITORING: String level monitoring provides highly accurate granular insight into system performance.
As the diagram above shows, each string in your system becomes an independently reporting node, allowing you to
detect and locate underperforming areas of the system with the highest degree of accuracy. String monitoring is the
best way to catch performance issues small enough to go undetected in gross generation data (but which can add up to
thousands of dollars’ worth of lost production over time). This level of monitoring granularity is highly recommended
for larger systems to help ensure optimum performance across all areas of the array.
2 SUB-ARRAY MONITORING: Sub-array (zone) level monitoring breaks out your array into several independently reporting
zones. If you have a problem area in your array, that zone will show a dip in production relative to neighboring zones,
alerting you to an issue that might have gone unnoticed in a system with basic monitoring only. When you do have a
problem, you’ll be able to use zone data to locate the trouble area more quickly, saving time and money.

You will need a separate zone meter (DC transducer) for each zone in your system...
a DECK sales agent can help you plan a zone map to match your specic system
needs. Each meter requires a separate data reporting charge.

sub-array monitoring
DECK can help you source the appropriate smart combiner hardware needed to meter
all strings in your system. Plan your total map of strings and combiners, then add the
appropriate additional data reporting charges. A DECK sales agent can help you plan
the system map and build an accurate quote.
