3.3.3.2. reactive current compensation
The XRGI system has 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 0.76. Compensating for an XRGI
without taking the nature of the property itself into account is pointless, on a number of counts. With an individual compensa-
tion, multi-module systems would require multiple reactive current compensations. In addition, when XRGIs produce power
they not only reduce the power requirement from the utility company but also the reactive current allowance (even if the XRGI
does not generate any reactive power at all).
This means 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 20G-TO, having considered the matters above, this is available
as an accessory.
The IQ-Control Panel is equipped with a grid monitoring relay according to DIN VDE 0126-1-1. A safety switch “accessible at
all times” is not required for individual systems.
