John,</div>
<div> </div>
<div>I guess you could sum up your excellant battery survival guide by suggesting that all installers insist that their customers should add more solar it they are not getting fully charged daily( or at least every few days). I am finally having the enjoyment of watching (with a WattMetrics monitoring system) one of my off grid customer's recent doubling of his solar array and seeing the perfect bulk, absorb, float senario on a daily basis. PV panels are now cheaper than buying batteries so if someone has a large battery bank, they owe it to themselves and their batteries to properly power them. Any of you not into remote monitoring yet, check out <A href="http://www.wattmetrics.com">www.wattmetrics.com</A> and look at Indian Pond site. This site is a two hour drive away and the owner has hired me to make sure the system is up and running at max efficiency at all times. .</div>
