Its size is measured by kVA, which is enough to supply power to your batteries. You can use this using cloudy or rainy days to back up your power source. In case your battery is already running empty, you have the option to get a generator. To sum it up, you need the following for your off grid solar system packages: You can have it attached directly to your panel, but there is also an inverter between your panel and the batteries. In comparison, solar produces a DC or Direct Current, and we need to convert it to AC to use it. Our appliances run using AC or Alternating Current. And that is because, on rainy days, they won’t be able to store power that much. If you use them during rainy days, you should use a battery with high storage and an additional panel. The solar charge your battery, and the battery distributes the power. Please take note that it is not solar power that makes the bulb lit up. Otherwise, it won’t charge your batteries. But for that to happen, you need at least 1600 watt-hour of daylight. However, this is not the case in using off-grid solar.įor example, a 100-watt solar panel can light a 100-watt bulb load for three nights. And the reason is we know our power source can handle it. Unlike our wire electricity connection, we don’t really calculate our loads or appliances usage before purchasing them.
