3. Product Introduction
3.1 Basic Features
3.1.1 Function
The RECOM RCM 4~25-TP-D series is a three-phase grid-connected PV inverter which used to
eciently convert the DC power generated by the PV string into AC power and feed it into the
grid.
3.1.2 The RCM 4~25-TP-D series inverter contains 10 models which are listed below:
RCM-4-TP-D, RCM-5-TP-D, RCM-6-TP-D, RCM-8-TP-D, RCM-10-TP-D, RCM-12-TP-D,
RCM-15-TP-D, RCM-17-TP-D, RCM-20-TP-D, RCM-25-TP-D
3.1.3 Applicable grid type
The applicable grid types for the RECOM RCM 4~25-TP-D series are TN-S, TN-C, TN-C-S, IT and
TT. When applied to the TT grid, the voltage of N to PE should be less than 30V. See Figure 3-1
for details:
3.1.4 Storage conditions
1) Inverter must be stored in its original packaging.
2) The storage temperature should be in the range of -30 ° C and + 60 ° C , and the relative
humidity stored is less than 90%.
3) If a batch of inverters needs to be stored, the height of each pile should be no more
than 6 levels.
