Battery Storage (EESS) Commissioning Certificate software

What this certificate includes

• You choose the sector, domestic, commercial or industrial, and it decides the fire-safety section: a dwelling follows PAS 63100, commercial and industrial premises follow the fire risk assessment route under BS 7671 Chapter 57. The certificate cannot be issued until a sector is chosen.
• On a dwelling, the installer confirms the battery is not sited in a PAS 63100 prohibited location, with itemised answers for sleeping rooms, cellars or basements without external access, outdoor clearances, stored flammable materials and the escape route. An itemised answer that contradicts the overall confirmation stops the certificate being issued.
• On commercial and industrial premises, the installer must confirm the premises fire risk assessment was considered in choosing the battery location, and can record its reference and date, a siting rationale, fire detection, ventilation, and segregation from escape routes and combustibles.
• A domestic certificate carries a PAS 63100 statement of conformity, with an answer for each subject it covers. Declaring full conformity while any answer is non-conformant blocks issue, and so does declaring conformity with exceptions without listing them.
• The battery system section records the chemistry, make, model and serial number, nominal and usable capacity, nominal DC voltage, maximum charge and discharge power, the battery management system and its firmware version, the number of modules and enclosures, and the MCS MIS 3012 integration class.
• The inverter section records the make, model and serial number, the rated AC output, any export limit, the DNO and the ENA connection route. A G98 route prints the factory-fixed settings note and the DNO notification details; a G99 route prints the DNO protection settings schedule and the values programmed into the inverter.
• The number of phases must be recorded whenever a G98 or G99 route is chosen. On a G98 route, a capacity above the G98 limit for that phase arrangement is flagged before you issue, and a battery recorded as providing an island or backup supply blocks issue.
• The test results cover DC insulation resistance positive and negative to earth with the test voltage, AC insulation resistance, polarity, loop impedance and fault current in charging mode and, where there is a backup supply, in island mode with its own earthing arrangement, plus the RCD test and the test instrument with its calibration date.
• A DC insulation reading below the minimum for the circuit, judged on its nominal DC voltage and whether it is SELV or PELV and never on the test voltage, an AC reading below the minimum, unconfirmed polarity, a failed loss-of-mains test or a failed charge and discharge test is flagged before you issue.
• Boost and float voltages, charge rate, low-voltage shutdown and boost time are recorded as configured. The certificate states that these are not compared against the manufacturer’s datasheet, so they are verified directly against it.
• Ventilation, the DC isolator rating and location, AC isolation and the emergency shutdown procedure are recorded, with the battery-presence notices at the origin, the metering position and the consumer unit. A required notice recorded as missing blocks issue.
• An arc flash assessment can be recorded with its reference, the assessed incident energy and its unit. On a dwelling, a figure in cal/cm² above the PAS 63100 limit blocks issue; a figure in any other unit is flagged for checking rather than converted.
• The certificate covers installer-completed commissioning up to industrial-premises scale. A recorded capacity or discharge power at grid or utility scale raises a warning that the system is outside its scope.
• A DC- or AC-coupled battery can name the Solar PV certificate it is paired with, and the associated EIC by number and date. Page 1 explains that this record accompanies the EIC, the MCS certificate and the DNO connection approval, and replaces none of them.
