Brian, We often have customers that don't want to loose programming for their satellite receiver. To reduce tare loss and the parasitic drain on a large inverter, we install a 100 Watt dedicated inverter, about $20, to keep the sat receiver going 24/7. We do the same thing for small refrigerators.
William, As for 28 year old batteries, I MUST know more. How did you verify the age? What make/model? Not knowing the history, I would not trust SG readings to determine condition. I have heard and seen all kinds of strange things done to batteries including dumping out old electrolyte and refilling, adding acids, salt water, aspirin, other chemicals and so on. Please tell us more. Larry On Dec 10, 2013, at 2:10 AM, Brian Teitelbaum <bteitelb...@aeesolar.com> wrote: "... The satellite unit may lose its programming when switched off which is a major hassle, so your client may not want to put it on a switch." From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of William Miller Sent: Monday, December 09, 2013 7:56 PM To: RE-wrenches Subject: [RE-wrenches] Heart Interface Idle Draw Friends: I have a client with 28 year old batteries. They are in great shape with excellent specific gravity. I have no idea why they have lasted so long. We recently pulled an old Heart HF series inverter and installed an Outback VFX3524 inverter. Coincidentally the client purchased a new flat screen TV and satellite receiver. The client reports generally lower battery voltages since the install. I am trying to figure out if it is the inverter or the TV. Does anyone know the idle draw of the HF series inverter? This information would help me troubleshoot this problem. Thanks in advance. William
