FV - PV string protection boards (DC and DC-AC) up to 1000 V DC
Country: · Model: FV
FV boards are assembled and wired for photovoltaic plants with DC voltage up to 1000 V and current of 63 or 125 A. They are installed between the strings and the inverter, where they combine the strings, protect against overload and surge voltage, and allow a section to be switched off.

Description
The enclosures are based on Indubox and polyester cabinets, are ready for outdoor installation and comply with UNE HD 60364-7-712. ECO-DC boxes bring several inputs into one output. Models FV211016-63, FV311016-63, FV411016-63 and FV511016-63 have 2-5 inputs and up to 63 A DC, while FV511016-125 and FV611016-125 have 5-6 inputs and up to 125 A DC. The supply set includes fuse holders for 1000 V DC, a surge protective device with a signal contact, a 63 A disconnector (a 125 A version is possible) and MC4 connectors; 10×38 fuses are bought separately. DC-MPP boxes from FV111016 to FV661016 take 1-6 strings to the same number of outputs, for inverters with several MPP trackers. Standard fuses are 16 A 1000 V DC, and 12 or 20 A are available to order. DC-AC boards, for example FVDCAC1114, add a circuit breaker, an RCD and a surge protective device on the AC side. The protection degree of the boxes is IP65, and the range of enclosures covers IP40-IP66.
How to choose
First count the strings and the current. For a single inverter input, an ECO-DC for 63 A suits 2-5 strings, or for 125 A it suits 5-6 strings. For an inverter with several MPP trackers take a DC-MPP, where each string has separate protection, and for an AC output a DC-AC is needed.

FAQ
What are the maximum voltage and current of FV boards?
Voltage is up to 1000 V DC. ECO-DC is made for 63 A and for 125 A, and in DC-MPP the current is set by 16 A fuses, or 12 or 20 A to order.
Are 10×38 fuses included in the set?
Cylindrical 10×38 fuses are not included with ECO-DC boxes and are selected separately. The set contains only fuse holders for 1000 V DC.
What protection degree does a board for outdoor installation have?
The boxes have IP65, and enclosures for PV plants range from IP40 to IP66.
Which standard do the boards for PV plants comply with?
Assembly is done to the requirements of UNE HD 60364-7-712 for photovoltaic installations.
