A lithium pack also makes your system 15 to 20% more efficient charging. And up to 40% more efficient discharging.
Lithium has a longer lifespan. It is recyclable. Safer. Virtually no maintenance.
There are those who will mistake operational needs for problems. Nothing can be done about that. Engineer solutions is what most of us do.
Some folks who own pb based systems still argue. Woad faces are common. But a couple years ago
Princeton researchers proved what lithium folks have been saying. Right now lithium is cheaper on a per cycle basis than pb.
To go off grid is completely within reach. And I would suggest, the moral responsibility of those with the brains and budget to do so.
A Tesla battery or two (now available). An SMA inverter (now available). Few solar panels. Day to put it together. No worries.
