What is EARU and what solutions does it provide for photovoltaics?

EARU is a brand of electrical equipment focused on circuit protection in photovoltaic installations. Its range of MCB automatic switches for 1000 V DC with 2 poles allows for disconnection and protection of panel strings and battery lines, integrating into electrical panels via DIN rail. It is a practical option for residential and commercial projects seeking reliability, availability of ratings, and a good cost-performance ratio.

Advantages

  • Specifically designed for direct current up to 1000 V DC (2P: simultaneous disconnection).
  • Common ratings: 20 A, 25 A, 32 A, 40 A, 50 A, and 63 A for strings and batteries.
  • Modular DIN rail mounting: quick installation and replacement.
  • Compatible with DC protections for surge and disconnection.
  • Good availability and contained cost for compact panels.

Applications

  • Protection of PV strings in DC structures.
  • Disconnection of battery lines in 48 V systems and LV banks.
  • Field panels and main panels for on-grid/off-grid inverters.
  • Small commercial installations with multiple MPPT.

How to choose the right DC MCB

  • Voltage: confirm that the system does not exceed 1000 V DC at minimum temperature (corrected Voc).
  • Rated current: size according to string Isc and manufacturer’s safety factor.
  • Number of poles: 2P to disconnect both positive and negative in DC.
  • Curve: use a curve suitable for DC according to the model’s technical datasheet.

Compatibilities Standard panels and DC protections

Best practices

  • Calculate Voc at low temperature and select the appropriate MCB voltage rating.
  • Apply derating for temperature and grouping in the panel.
  • Combine with SPD Type II DC and main disconnection according to regulations.
  • Label polarity and circuit; verify tightening torque and conductor cross-section.
