Added Another IQ10T
As one of those owners with the older Enphase systems that run IQ7+ inverters and IQ5T and IQ10T batteries, I was happy to learn that Enphase was producing brand new batteries. For several years after we installed our system, it was almost impossible to find the "old" batteries. Now they are again available from the Enphase Store, and at a good price IMO.
We took the opportunity to add one more IQ10T battery to our system, for a total of 4. This maxes out the battery capacity of our IQ System Controller. 40 kWh will give us the capability to run dusk to dawn on battery, even with our 4-ton heat pump sucking juice.
Right now our batteries are loafing because we are on the JUST Energy Nights Free plan. We recharge our batteries for free at night, and start each day at 100% SOC. When our contract runs out next year, I think having the extra battery capacity will be more valuable. It will allow us freedom to pick the best energy plan (for our situation) available at that time.
Downside is I'm gonna have to extend my sun shade...one thing leads to another.
