Thanks for the tip! I'll check the firmware. Dave Angelini Offgrid Solar wrote on 7/22/19 9:11 AM: Hi Jeff, I am not going to guess if this will work, it should.  I use XW's because they start anything I have come across. If you do this, make sure but SW's have the latest and same firmware.

Thanks Ray for the data comparison - yes unfortunately they are on a high hill and need to 2 HP - it's a monster! Ray wrote on 7/22/19 9:53 AM: I have a macerator in my basement, I just measured it, and I was hitting roughly 1100 watts peak for 1 sec.  I don't know what the Hp rating is, but

Re: [RE-wrenches] Large Off-Grid Residential System and ciculating currents

William I have a few blue ion installs that was used for testing. I used eguage to monitor all DC in and out of each stack of 16k with no issues. The BMU manages everything and can be chained to each other to reduce or even prevent that issue. I have seen Blue Ions original stacks greater then 100

Re: [RE-wrenches] Large Off-Grid Residential System and ciculating currents

Friends: I am a complete newbie to any lithium technologies, so please forgive some newbie questions: I am used to working in amp hours. If we are looking for a battery bank in the range of 100 kWh, this converts to about 2,083 amp/hours at 48 VDC. Is my arithmetic correct? An on-line calc

Hi William - Check out the Solarpro Magazine archive May/June 2017 issue page 34: it addresses "functional grounded PV systems." https://docs.wixstatic.com/ugd/d49ff9_ccc99efe7b344f6a945ca2e00f8a71d8.pdf And the definition found in 2017 NEC 690.2: [image: image.png] Yes, the normally grounded w

Re: [RE-wrenches] DC Bonding battery systems

Wrenches – I am no code expert, but wanted to chime in to this important discussion. Rapid shutdown (690.12) does not deal (directly) with arc faults at all. The initiation of rapid shutdown is generally a manual process that a first responder triggers to reduce shock hazard. The RS system is

Hi William - This article is a few years old, but I think describes ground fault detection issues well: http://www.solarabcs.org/about/publications/reports/blindspot/pdfs/inverter_groundfault-2013.pdf I don't have experience (at least since the late 90s) with the type of GFD breaker you describe

[RE-wrenches] To Bond or Not to Bond the Neutral to Ground

Hey Wrenchers, I have been having a design debate with several associates regarding bonding the Neutral to the Ground for Line Side grid connections. In the fused solar AC Disconnect located closest to the Service Line Side grid connection should the Neutral be bonded to Ground? What Article in
