Your feedback is highly appreciated. With the depth analysis of the whole system, we found the max. discharge current for batteries even reaches 4000A, which is extremely high current for low voltage (48V) battery systems.For example, facility number 1 of lot 1 (Al Maharah Governorate Vaccines Warehouse), the maximum charging current is 1100A (11 charge controllers x 100 A @450Vdc) which could cause safety problems for the batteries. Therefore, is it possible to accept the high voltage of the battery bank instead of 48V?Response: Please be advised that all applicable safety requirements have been thoroughly addressed and incorporated into the design, and the provided assumption is not correct as the discharge current related to the inverters which is already considered in the design. Therefore, all bidders are strictly required to comply with the minimum design specifications as outlined in the tender documents. Clarification 64: Kindly be noted that in the cross section area of earthing system are not same in some drawing, for example in lot No 1 system in Taiz and Marib the cross section of earthing cable are 16mm2 but another system  the C.S is 10mm2.

Could you please provide clarification on this?Response: Please refer to the same BoQ, item# 26.1 which mentions the stone construction work for the water tank.Clarification 9: It would be highly appreciated if you grant an extension of the deadline enabling us to submit our suitable offer.Response: An amendment is created to extend the submission deadline and the clarification deadline as follows: Tender Submission deadline to 30 April 2025Clarifications deadline to 24 April 2025Please refer to the eSourcing general tab with the amended datesClarification 10: Solar Battery: For the battery the manufacturer worried about the safety risk because of this point With the depth analysis of the whole system, we found the max. discharge current for batteries even reach 4000A, which is extremely high current for low voltage (48V) battery system. We accept Max. discharge current 500A, and current design of the tender required will cause huge risk of the safetyResponse: Please be advised that all applicable safety requirements have been thoroughly addressed and incorporated into the design, and the provided assumption is not correct as the discharge current related to the inverters which is already considered in the design. Therefore, all bidders are strictly required to comply with the minimum design specifications as outlined in the tender documents. Clarification 11: Referring to the esourcing under Document Check List there is a requirement of Key Personnel while the Evaluation Criteria of this RFQ say: The recommended bidder must submit key personnel details within 8 calendar days of notification of potential selection. ● If the bidder fails to fulfill the above requirement within the set timeline, UNOPS reserves the right to award the contract to the second-ranked or second-lowest-priced compliant bidder.Response: ​The requirement in the checklist tab is "Schedule 3 - 3.9 Key Personnel Requirements - Filled, and Signed/Stamped" where bidders are required to only sign and stamp the mentioned schedule from the document "All Lots - RFQ-2025-570111 - Solicitation Sections II, III, IV, V" which is considered to be as a confirmation from the bidders' end that they will abide by the minimum requirements of key personnel in case they are requested.Clarification 12: Will  you please consider the Minimum capacity of solar panel 700wp instead of 650wp as all solar panel manufacturers had stopped production models from 650wp to 695wp.Response: Please note that the PV module capacity specified in the Bill of Quantities (BoQ) is "not less than 650 Wp". Accordingly, any capacity above 650 Wp is acceptable.Clarification 13: With the depth analysis of the whole system, we found the max. discharge current for batteries even reaches 4000A, which is extremely high current for low voltage (48V) battery systems. For example, facility number 1 of lot 1 (Al Maharah Governorate Vaccines Warehouse), the maximum charging current is 1100A (11 charge controllers x 100 A @450Vdc) which could cause safety problems for the batteries. Therefore, is it possible to accept the high voltage of the battery bank instead of 48V?Response: Please be advised that all applicable safety requirements have been thoroughly addressed and incorporated into the design, and the provided assumption is not correct as the discharge current related to the inverters which is already considered in the design. Therefore, all bidders are strictly required to comply with the minimum design specifications as outlined in the tender documents. Clarification 14: In the BOQ part of 18.1.2 Smoke detector and 18.1.3  Heat detector , there seems to be a mistake in the Sensitivity according to EN 54-10.
