Inverters. Minimum of ten (10) years product warranty from date of sale to first consumer purchaser for product workmanship and materials.
Inverters. Inverters shall be string inverters and have a NRS 097-2-1 (2017) inverter compliance certificate from a third-party test institute. The Contractor shall provide inverter arrangement for the PV Plant that is selected to give overall optimal energy yield from the PV Plant over the life of the Contract Period, taking into account the site conditions, the proposed module layouts, shading and orientations. The inverters shall be installed in a manner that it is not exposed to direct sunlight. Inverters shall meet the following general requirements: Due to maintenance reasons and a conservative spare-part approach, inverters of the same type and size from the same manufacturer shall be deployed. Inverters shall be equipped with communication capabilities as required by the Control and Monitoring System (CMS); all inverters shall be able to be controlled / supervised by the same software or CMS system. Software must be paid for or free access for the Client for the lifetime of the plant. Inverter specifications shall be selected with respect to the local climatic and environmental conditions. The inverters shall be suitable for inland installation and operation in conditions such as extreme heat and dust. Inverters to be used shall be reliable inverters with a proven track record in performance, operation and obtaining long-term debt (project finance). The manufacturer shall be established in the market. Inverters must comply with applicable norms and standards including but not limited to NRS-097-2- 1:2017. The test result and certification must be attached to Returnable Technical Schedule, Inverters shall comply with South Africa Grid Code requirements for renewables. The Contractor shall submit calculations for ensuring electrical compatibility between the inverters and the modules selected including, selection of appropriate inverter dimensioning factor and ensuring system voltages lie within acceptable MPPT ranges across the range of operating conditions for the Site. The quality of equipment supplied shall be generally controlled to meet the guidelines for the design included in the standards and codes listed. All transportation, storage, handling and installation of the inverters shall be in accordance with the specifications from the manufacturer to ensure that the manufacturer’s warranty is honoured. The Contractor will be required to confirm the inverter manufacturer’s warranties for the given environment and installation type. The Contractor shall als...
Inverters. 3.1 The inverters shall be one of the inverter models detailed in the Project Developer’s Technical and Feasibility Specification unless otherwise agreed with the Ministry in its absolute discretion.
Inverters. In addition to the above, inverters proposed by Xxxxxx must comply with the following: • Inverters shall be suitable for grid interconnection and shall be compliant with all Utility interconnection requirements, including those requiring rapid shut-off capabilities. • IEEE 929-2000 – “Recommended Practice for Utility Interface of Photovoltaic Systems”. • Inverters shall be listed to UL 1741 standards and tested for IEEE 1547 compliance. • Inverters shall be CEC-listed with an efficiency of 95.5% or higher. • Inverters must automatically reset and resume normal operation after a power limiting operation. • Inverters shall be sized to provide maximum power point tracking for voltage and current range expected from PV array for temperatures and solar insolation conditions expected for Project conditions. • Inverters should be equipped with D.C. Ground fault protection to reduce fire hazards in grounded array configurations. • Enclosures shall be rated NEMA 4 when the inverter is located outdoors. For outdoor installations in corrosive environments, NEMA 4X enclosures must be used. • Inverter selection shall take into account anticipated noise levels produced and minimize interference with Purchaser activities.
Inverters. 2.11.1.1. Line-commutated inverters do not require synchronizing equipment.
Inverters. The inverters proposed by Offeror shall comply with at least the following: • Inverters shall be suitable for grid interconnection and shall be compliant with all interconnection requirements. • IEEE 929-2000 – “Recommended Practice for Utility Interface of Photovoltaic Systems”. • Inverters shall be UL 1741 and IEEE 1547 compliant. • Inverters shall be CEC-listed with an efficiency of 95.5% or higher. • Inverters must automatically reset and resume normal operation after a power limiting operation. • Inverters shall be sized to provide maximum power point tracking for voltage and current range expected from PV array for temperatures and solar insolation conditions expected for Project conditions. • Enclosures shall be rated NEMA 3R when the inverter is located outdoors. For outdoor installations in corrosive environments, NEMA 4X series 300 stainless steel enclosures must be used. • Inverter selection shall take into account anticipated noise levels produced and minimize interference with Department activities.
Inverters. CoolEarth shall supply either SolarEdge SE20kUS or SMA STP24000TL-US inverters. Approximately 4 units.
