backchannel: overkill solar

from a reddit comment:

400 watts is going to be overkill for a [100Ah LiFePO4] battery

Depends on what we mean.

At max practical harvest a 400w panel feeding a 100Ah LFP would be ~0.27C, well within the comfortable charging range of the battery. “Overpaneling” the bank has a few advantages:

• better harvest in poor conditions
• better support for loads
• allows recharging in a shorter window of time
