Page 17: Installation
Installation Safety instructions Do not remove the upper casing. The inverter contains no user-service able parts. All servicing must be performed by qualiﬁed service personnel. All wiring and electrical installation should be performed by Warning! qualiﬁed service personnel and must meet national requirements. Both AC and DC voltage sources are terminated inside the APV-S Inverter.
Page 18: Mounting
• Be careful not to obstruct the slits or the equipment cooling systems. • DO NOT place anything on the inverter while it is working. Mounting The inverters must be positioned so as to ensure free movement of ventilation air around them and facilitate wiring and maintenance operations.
Page 19: Mounting The Inverter On The Bracket
(1)U se the mounting bracket as a template, ensure it is positioned horizontally. Drill 4 holes in the wall in correspondence with the holes on the bracket shown in the ﬁgure. Attach the bracket to the wall with 4 M10 screws (not supplied). The size of the holes depends on the wall material and the anchorage system used(e.g.
Page 20: Electrical Connection
The system configuration depends on many factors (module type, production target, AC connection, installation site, current regulations, etc.) and must therefore be designed, built, and decided by a qualified technician. The Radius Planner program, downloadable from www.rishabh.co.in, can help you correctly size the PV module strings. Safety Connect the ground connector to the terminal (PE) of the APV-S inverter.

Removing the backup battery protection The APV-S inverter is equipped with a backup battery. Remove the protective plastic tab during installation/programming. See “Figure 38 : Position of battery on electronic card” on page 85.
Page 26: Fixing Of The Lower Panel
Fixing of the lower panel Reposition the lower panel by tightening the 6 torx T25 screws shown in the ﬁgure. Recommended tightening torque 4.5 Nm. In order to maintain IP65 protection level of the inverter, the recommended tightening torques must be ap- plied whenever the lower panel is repositioned.
Page 27: Dc Side Fuses And String Current Monitoring
DC side fuses and string current monitoring 6.7.1 DC side fuses ( MC4 with Fuse -F models) The DC side fuses are very useful because in case of a malfunction or short-circuit of a string module or cable they trip and eliminate the defective string. This prevents the currents from all of the other strings in parallel from contributing to the short-circuit.
Page 28: String Current Monitoring
Model Fuse Quantity gpV / 1000Vcc / 12A (*) 24 (12+12) APV-S-50k-AE-TL-2.F.. (*) 12A is the standard fuse size installed in the factory. Other fuse sizes (type gpV / 1000Vcc) can be installed according to the instructions of the PV module manufacturer. These fuses can be ordered on request. 6.7.2 String current monitoring This function is included in the -F models.
Page 29: Ground Kit
GROUND KIT The ground kit is needed only for thin film or back contact modules where specifically required by the manufac- turer. It is available for grounding either the positive or negative pole by means of a 1A fuse. The inverter with ground kit must be requested at the time of order; specify the polarity to be grounded. Inverters with ground kit must be connected to the grid by interposing an isolation transformer in order to have galvanic separation.
Page 30: Ac Side Fuses
/ 125A 6.10 Choice of leakage breaker on AC side Rishabh string inverters are equipped with a protection against ground faults in conformity to German safety standard VDE 0126-1-1. Specifically, they are equipped with a redundancy reading of leakage current to ground applicable to all current components (both DC and AC). Leakage current to ground is measured simultaneously and independently by two different processors. The protection trips if one (or both) of them detects a fault, with consequent disconnection from the grid and stop of the generation process.
Page 31: Dc Circuit Breaker
6.11 DC circuit breaker The DC circuit breaker is connected downstream of the fuses and galvanically disconnects the DC source on the AC side. Breaking is done simultaneously on the positive and negative poles of all MPPT present. Warning: the DC circuit breaker DOES NOT switch off the AC side. Warning!

Page 71: Rs485 Serial Connection With Modbus Rtu Protocol
Communication is performed via RS485 serial connection with MODBUS RTU protocol. To configure communication between the inverter and the monitoring/software system, you have to respect numerous elements in order to ensure correct functioning. You can connect and communicate with a maximum of 50 nodes. DO NOT exceed 250 meters for the commu- nication line (for longer lengths please contact Rishabh Solar Service). In case of communication between a single inverter and a PC (with supervision SW or inverter configuration SW installed), you need to use a USB - RS 485 converter cable (we recommend our cable code 8S8F60 length 1.8 meters or code 8S8F61 length 5 meters (laboratory tested); other “passive” converters may not work).
Page 72 APV-S (3) USB 485 converter (1) supervision PC or configuration SW. Note! The first and last element of the modbus chain must have the termination resistor inserted. APV-S: S2 / S3 (Switch): see Figure 27. Radius Log Int (see Figure 35) TM (Switch): OFF = termination resistor not inserted; ON = termination resistor inserted (120 Ω). If RADIUS LOG-INT is present, you can connect only one monitoring device.
Page 73: Master/Slave Alarm Monitoring And Remote Control Functions
Master/Slave alarm monitoring and remote control functions These functions can be useful when the APV-S inverters are positioned in different, hard-to-reach, points of the system. The inverters have to be connected via RS485 serial with MODBUS RTU protocol, as shown in the figu- re below. See section 9.1 for further details. Note! The first and last element of the modbus chain must have the termination resistor inserted. See Figure 27.
