On regular solar systems you *must* disconnect load before disconnecting the PV array (to prevent damage). Can the remote On/Off (wired - usually a link.. wired in the Easysolar units) on the 250/70 be used to shutdown the output of the MPPT safely (without risking damage to any component)...?
Reason: I have a situation where I am in ESS mode and if the power goes out everything still runs via battery and/or solar.. however the backup generator starts and the easysolars must not attempt to export whilst running on generator.. so was thinking as part of the generator changeover of hooking up another relay to “remote on/off” the MPPTs (one or more) to ensure when running on generator solar is not available... not ideal, but there is no way for ESS to know whether it’s running on generator or not, and no way to otherwise limit export on command (or even switch to hub-1 mode when power is not grid supplied.
Thanks,
