[RE-wrenches] Need some help

[Tump]

If you have the old BP 585 watt modules I would strongly suggest that you scrap the whole system.  Take advantages of better performance modules & inverters and IF the client may have tax liabilities then they can discuss the additional tax benefits of a new system with their accountant. those old BP 585 were around in the late 90s.

It is a gas station that has 20 KW worth of solar on the canopy, two Trace PV-10208’s and two transformers, one on the output of each inverter. The system was shut down during a large renovation, wires cut and sort of lost under the pavement during the work. We have a good idea where we can dig to locate the conduit for AC but my dilemma is the equipment on the canopy. The owner has no idea how old the system is and if it was actually working prior to the reno.

Power supply at gas station is 208. So, please and thank you in advance, any and all help, guidance and ideas greatly appreciated.
