<div dir="ltr">Hi William,<div><br></div><div>Think of Namaka as the collector of the true SOC and other BMS data on the batteries. It also acts as a data translator for BMS data to other communication protocols. For other inverter brands it can speak directly to the equipment via Canbus or RS485. I think it's valuable to be able to view past data and see what the BMS is seeing. Provided you can get the Namaka connected to the internet, the data is hosted on <a href="http://stellar.newsunroad.com">stellar.newsunroad.com</a>. As an installer you can get a portal view of all your Namaka systems regardless of the inverter brand.</div><div><br></div><div>The Flexnet DC seems to do quite well calibrating to the Radian provided that the system is getting full regularly (up to 55V). I like to start my generator at around 15% and also trigger the generator between 49V-50V. Having a 2-min voltage start covers you in case your SOC gets uncalibrated. This seems to be between 5-15%. Blue Planet has Outback integration guides and I am happy to send one off list that will help you get started.</div><div><br></div><div>It sure doesn't seem like retirement worked out!</div><div><br></div><div>Good Luck</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 1, 2022 at 12:06 AM William Miller <<a href="mailto:william@millersolar.com">william@millersolar.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div class="gmail-m_48970877927996877WordSection1"><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Friends:</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Thanks for all of the input about the Blue Planet 8kWh configuration. Here is the story: The red lead is supposed to be longer. It is supposed to have enough slack looped behind the panel so you can pull enough out to connect to the second from bottom shelf. There was a redesign and the extra length got accidentally deleted. Blue Planet apologized for the problem and pledged to correct it.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">I cut the wire ties holding the existing red lead and rerouted it to reach. It is not elegant but it works. We fabricate cables so I will make a longer 2/0 cable to make it look right. I would have done this right away but it seemed like I was missing something.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Jody of Blue Planed was very helpful.

It is called the \u201cstacking kit\u201d but it does allow wall connection of a one-high cabinet. I fastened two chunks of strut securely to the wall with Simpson SDS lags, one high and one low, and bolted the cabinet to the strut. I used two existing holes in the cabinet up high and drilled two more down low.</span></p><p class="gmail-m_48970877927996877MsoListParagraph"><span style="font-size:12pt;font-family:Verdana,"sans-serif""><span>3.<span style="font:7pt "Times New Roman""> </span></span></span><span style="font-size:12pt;font-family:Verdana,"sans-serif"">There are ground straps that need to be removed from the door and the top for those panels to come off. It would be very easy for these straps to contact the positive terminals in the front or top. Keep them secure or tape them off.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">I have another question: The Namaka chassis is a $900 add-on. When I asked if it was necessary, I was told it was needed to pass SOC data to the Radian. I had the presence of mind to ask what the Radian does with the SOC value and I was told, \u201cnothing.\u201d Apparently that is a future thing. Also the Namaka is supposedly needed to provide user data on SOC. Apparently this tells the user when they are about to run out of power via the Namaka web site. I looked around and I cannot find the Namaka web site. Am I missing something? Do I need this unit?. </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">One of the characteristics of Lithium batteries is the flat voltage curve during discharge. I have been aware of this fact but I am not sure I thought through the implications. This is going to make it hard to call battery voltage triggered actions, like starting a generator or sending a notification email. So if the Radian cannot process Namaka SOC data and the battery voltage caves suddenly at the bitter end, how do we start the generator or send low battery notifications? Will the Namaka web interface fill in these gaps? I am sorry if I am being dense here, but these seem like valid concerns. I am prepared to be taught that I am totally missing something.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Thanks to all of you for being the awesome people you are.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">William Miller</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,"sans-serif"">Miller Solar</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,"sans-serif"">17395 Oak Road, Atascadero, CA 93422</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,"sans-serif"">805-438-5600</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,"sans-serif""><a href="http://www.millersolar.com/" target="_blank">www.millersolar.com</a></span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,"sans-serif"">CA Lic. 773985</span></p><p class="MsoNormal"> </p><p class="MsoNormal"> </p></div></div>
