Losing power anytime is bad. But it is really bad in the summer. For the areas along the US coasts where the hurricanes hit, we need our air conditioning in the summer. Losing power in the hurricane is bad. But when the hurricane is gone, the heat comes back.
Portable generators are a cheap way to have some power. The downsides: buying fuel, running electric cords, noise and maintenance. You can mitigate the second part by buying and installing a manual transfer switch. This lets you power the house with the generator. Maintenance: most portable generators need to have the oil and spark plug changed every 50 hours. That is every other day! This matches with your lawnmower, once a year oil change and plug = 50 one-hour mowing jobs. And portables are noisy.
Permanent installed are great. They eliminate the short-term issues above and the power cords. But most still require maintenance every 100-200 hours or 4 days to 1 week, depending on model and size. You also lose power for at least 30 seconds to a minute until the generator starts. Permanent generators have better sound insulation and are quieter than portables. But they still make noise.
In any case, if you have a grid-tied solar system, they cannot be used during a power outage. UL 1741 requires this, to prevent back feeding the power grid. And a generator does not work well with solar panels.
With Mi-Grid, it is a hybrid solar energy system with PV panels, a battery bank, inverter/control system, transfer switches (if needed) and backup generator.
With battery-based inverters, power switches in milliseconds, as soon as the power goes out, typically in 1/60th of a second. The solar system is designed to work off-grid, so it keeps producing power, even when the utility is out. And if solar energy is not enough or your power usage is high, the generator can supplement your power and recharge batteries. This means the generator doesn’t run all the time. Typical properly sized systems, the generator runs on average 2-3 hours per day. Heavy use days or days without much sun, it may run up to a total of 8 hours. Quiet hours can be setup for overnight, so the generator doesn’t disturb your sleep.
Finally, Mi-Grid can be setup to only cover your essentials: lights and outlets. Large appliances and whole house air conditioners will run only when the generator turns on. You can control how much time they run. And in most applications, you can still air condition one room all the time, with a window or mini-split air conditioner. For those on a budget, small solar and inverter with a large generator is the way to go. You can always upgrade the solar, inverter and batteries.
And Mi-Grid isn’t just for Hurricanes. It will protect you against any kind of power loss, while saving you electricity all year long.
