So yeah, it seems history repeats itself. The Redarc BCDC1225 is not reliable in switching between solar inputs and 12V input derived from the mains.
At least this morning’s wake-up call was a little later in the morning:
From: email@example.com To: firstname.lastname@example.org Subject: IPMI hydrogen.ipmi.lan Message-Id: <20171023194305.72ECB200C625@atomos.longlandclan.id.au> Date: Tue, 24 Oct 2017 05:43:05 +1000 (EST) Incoming alert IP : xxx.xxx.xxx.xxx Hostname: hydrogen.ipmi.lan SEL_TIME:"1970/01/27 02:03:00" SENSOR_NUMBER:"30" SENSOR_TYPE:"Voltage " SENSOR_ID:"12V " EVENT_DESCRIPTION:"Lower Critical going low " EVENT_DIRECTION:"Assertion " EVENT SEVERITY:"non-critical"
We’re now rigging up the Xantrex charger that I was using in early testing and will probably use that for mains. I have a box wired up with a mains SSR for switching power to it. I think that’ll be the long-term plan and the Redarc charger will be retired from service, perhaps we might use it in some non-critical portable station.
