Supply and Installation of JIC Solar backup System at Giwa Barracks Maiduguri

Dear Vendor, Kindly see attached revised RFQ based on the request for clarification. Below is an additional explanation in blue for your information, if there be additional query do no hesitate to reach out before the deadline. 1. Item 1&3: item 1 (15kva Quattro) is a Victron Energy product while item 3 (XW 100A MPPT Charge controller) is a Schneider product; as such both products cannot be combined together to work effectively as both products have different system communication protocols - They won't communicate. Yes Charge controller and Inverter is better matched for better communication and operation. Since we specified the brand we want them to buy, you can match the inverter and charge controller as GX control box is matching with inverter. 2. Item 2&3: item 2 (655w Solar panel by 40pcs) has a total capacity of 26.2KWp as such, one unit of 100A MPPT Charge controller cannot accommodate this PV capacity. This will require at least 5 units of 100A SCC. The number of solar panels in the BOQ requires at least 4 charge controllers of the requested capacity because 655W x 40pcs is 26KWp solar power and XW 100A 600V MPPT maximum output is 6KW and maximum input power is 7-8KW(oversized). 3. Item 4: Please we need clarification in respect to the battery options (lead acid and lithium-ion), resultant capacity, quantity of each battery option because 24pcs of 2v/1000ah OPzV is 48KWh and 5pcs of 10KWh lithium-ion battery is 50KWh. The phrase should be 2V/1000AH OPZ battery or lithium ion battery equivalent, With that they will give the right quantity for Lithium if they choose to give lithium ion battery. Lithium ion battery Equivalent of 2V/1000A OPZ battery of 24pcs is 48KWH, so they can chose to offer it as 1pc of 48kwh or in 5pcs of 10kwh. Thank you IOM Maiduguri Tender
