HI Drake BE CAREFULL I had a battery set explode on me due to a loose connection, it had been charging, and I was investagating and the loose connection sparked and BANG I was fortunatle to have my goggles on. Besure to stop charging then vent, then investiagate. Also I do not think the w

You might consider using a gutter in lieu of the LB or a junction box if the site conditions are conducive. From: Marco Mangelsdorf To: RE-wrenches Sent: Sat, August 14, 2010 6:47:37 AM Subject: [RE-wrenches] Aluminum conduit LBs The lesson was that even if

The lesson was that even if, say, for a 2 ½ “ conduit says three 350 MCMs are OK, that doesn’t mean that a 2 ½” LB I was planning on using is rated for three 350s. For the first time ever I saw printed in the LB itself the specified max conduct size, in this case 4/0 for a 2 ½” LB. So for t

Any way she can get a real voltmeter?  the MX60 has voltage calibration, so does the FX  it sounds like something is over charging, perhaps the generator run?   additonal details on battery bank size, array size and typical load.    Darryl --- On Sat, 8/14/10, Drake Chamberlin wrote: From:

Drake, I'd start by having her disconnect the temp sensor. If it has failed, it can cause false voltage compensation. However, if the MX60 is reading higher than actual, as your post suggests, I would more expect it to regulate sooner, thus leading to less water

Hello Wrenches, I just got off the phone with an off grid system owner who has a voltage discrepancy showing between the reading on her MX-60 and both her Mate and Trimetric meter. The MX-60 shows 28.8 V and the Trimetric and the Mate both show around 25 volts. The batteries are using a tre
