MALAYSIAN STANDARD MS 1837 : 2018

INSTALLATION OF GRID-CONNECTED PHOTOVOLTAIC (PV) SYSTEM. (SECOND REVISION) 

MS 1837 : 2018 (Second Revision) was developed by the Working Group on Solar Photovoltaic Systems under purview of TC on Renewable Energies. This Malaysian Standard cancels and replaces MS 8137 : 2010 (First Revision), Installation of grid-connected photovoltaic (PV) System.

The standard outlines the general installation requirements for grid-connected photovoltaic (PV) arrays with direct current (DC) open circuit voltages up to 1500V between positive and negative conductors or up to ± 1500V with respect to earth and also includes the following PV array configurations, single string of modules, multistring PV array and PV array divided into several sub-array. DC systems and photovoltaic systems in particular, pose some hazards in addition to those derived from conventional alternate current (AC) power systems, including the ability to produce and sustain electrical arcs with currents that are not much greater than normal operating currents. This standard addresses the safety requirements arising from the particular characteristics of photovoltaic systems.

This standard is to provide guidelined on grid-connected PV system installation, electrical safety and fire protection requirements for : 

a) uninformed persons, including owner(s)/occupiers(s) and users of the premises where photovoltaic arrays are installed : 

b) incorporation of new requirement on "Protection requirements" in Clause 6;

c) incorporation of new requirement on "Wiring requirements" in Clause 7;

d) incorporation of new requirement on "Component requirements" in Clause 9;

e) incorporation of new requirement on "Marking requirements" in Clause 10; and 

f)  incorporation of new requirement on "Commissioning" in Clause 12
