![]() The oldest, and still the most cost-efficient, off-grid battery technology is flooded lead acid (FLA). The sun may not shine, the wind may not always blow, and even a stream’s flow may drop in late summer, so any off-grid system needs to bank electricity in a battery array-most cottagers will need enough for two or three “days of autonomy” without any power generation.Ī typical off-grid cottage battery bank will use lead-acid technology, although lithium-ion technology is rapidly improving. Here’s why the 2020s will be the decade of off-grid cottaging. In fact, almost everything about off-grid power generation is getting more efficient and more reliable-from the solar panels and the battery systems to the appliances that use the power. ![]() At best, they’re quirky tinkerers who go to bed early because both lightbulbs are flickering and they’re exhausted from a day of chopping wood and analyzing battery chemistry. Admit it, you cottagers who are tethered to the electricity grid: as much as you hate paying the utility bill, some of you secretly think cottagers who generate their own power are a bit eccentric, even downright weird.Īt worst, perhaps you think they’re apocalypse-any-minute-now preppers who look like Duck Dynasty extras and want to swap recipes for squirrel stew and tips for booby-trapping the property line.
