The control head Xantrex Link 1000 Remote for our Xantrex Freedom 30 Inverter/charger has become erratic and will need to be replaced. Xantrex no longer produces the Link 1000 Remote Model 84-2019-02, and I have not been able to get a response from Xantrex regarding a replacement. Has anyone found a replacement? The inverter/charger works perfectly so I do not want to spend another 3 boat bucks on a new one. Harry Hungate Bessie NT 32-238
