<strong>Yahoo Message Number: 100000</strong>Hi Folks,<br/><br/>Having added solar modules on the roof a few years ago and not using the inverter to maintain the batteries, I set the MPPT charger for 13.4 vdc. I appears that this has helped in the longevity of the batteries as they are at 95% after 8 years. <br/>Fred Kovol<br/><br/>2000 Allure 30593
