Business ProfileforMann Solar

On 4/28/2022 we purchased a complete solar system from Mann Solar for $5,122.45. After installment we made several calls to ******, at Mann Solar reporting fans in the inverter/charger were running continuously. I was told by ****** it was probably the thermostat but should not be a concern. He said if the fans stopped working, he could find cheap replacement fans on ******. On or about 4/22/2024 the charger/inverter unit stopped working. Default code in LED unit showed F-11. We contacted ****** at Mann Solar to report failure of unit. We were told to remove the inverter/charger unit and bring to Mann Solar. We removed the unit and it was taken to ******. He opened the unit and examined it. We were told the charge unit was out. He said he could not replace the unit. Stated he had purchased the unit with manufacture warranty only and could no longer reach them. He felt they had gone out of business. That he only sold the units and could not replace them. We were told by ****** that we could bypass the issue by purchasing a new solar charge controller and PV DC isolator switch. We purchased these items on 5/11/2023 for $491.84. With instructions from ****** we installed the PV DC isolator switch, controller unit and reinstalled the inverter/charger unit and recharged all six batteries. The unit continues to fail, showing code F-11 and shutting down. We again contacted ******, sending pictures and video of entire unit including battery pack, new PV DC switch, charge controller along with the inverter/charger unit while it was in default. ****** continues to evade responsibility. Please assist. Thank You
