But if you are replacing the Outback 2200 RE with 2100 AH and about 1100 AH usable, or @ 51V then 56 kWh with Lithium, 62 kWh, Do you have the charging capacity to charge at 280 amps? This is to allow full use of the solar array. One of the things I have found with LA batteries at high charge rates causes shortened battery life. Check with Harris for the maximum charge rate. You will be charging two in parallel the battery BMS will have to handle the BMS in each battery. Also, check the top balance current of the batteries to assure the low cells can be balanced in the perhaps 4 hours. The charge controllers will limit on voltage and the batteries will be in top balance current, is this ok with Harris? You will use multiple charge controllers, I try to set the voltages a little lower on two of the charge controllers to create a tapered charge. <o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Thu, Nov 4, 2021 at 10:50 AM <<a href="mailto:scot.arey@solarcentex.com">scot.arey@solarcentex.com</a>> wrote:<o:p></o:p></p></div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-right:0in'><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Does anybody have insight as to the Harris lithium battery and its use as a replacement for a RE2200 AGM that needs replacement?<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Our setup is dual Radian 8048s for a full off-grid home with 14KW of solar.
