The XRGI® system is equipped with a three-phase asynchronous generator, which not only generates active power but also, of course,
reactive power. The cos ∂ of the angle between active and reactive power is approximately 0.8. Compensating for an XRGI® system
without taking the nature of the property itself into account is pointless for a number of reasons. With individual compensation,
multi-module systems would require multiple power factor corrections. In addition, when XRGI® systems produce power, they not
only reduce the power requirement from the utility company but also the reactive current allowance (even if the XRGI® system does
not generate any reactive power at all). This means that the reactive current from machinery, fluorescent tubes, etc. is deducted from
the allowance and must be paid for. If a power tariff includes reactive current, it would therefore be advisable to include the whole
property in a viable reactive current compensation strategy.
If reactive current compensation is only required for the XRGI® system, having considered the matters above, this is available as an
accessory.
Allow only authorised EC POWER specialists to connect the Q-Network modules and the Load Sharer S. Install the modules on a
vibration-free foundation. Do not shorten, extend or cut-off the sensor and control cables for the Q-Network modules.
Q-Network modules are networked with other Q-Network Modules and the Load Sharer S with other Load Sharers S’s via a Q-Network
cable (SFTP (CAT 6) net cable). Make sure that any unused RJ45 connectors are covered with an RJ45 (8 × 8) ISDN network terminator.
