災害停電時の非常用電源 Emergency power supply when we have the disaster power outages

災害が頻発する日本では停電、断水など、万一に備えた準備が必要です。

停電時に代替供給電力源として発電機を使うか、蓄電池を使うかですが、我が家ではこの度、先ず、太陽光発電＆蓄電可能な小型のポータブル電源（定格電量2KW）を購入しました。

この電源でほとんどの電気製品が使用できるようですが、実際にどんな電気製品がどのくらいの時間使用可能かをテストして確認します。

我が家には通常の受電回路とは別に発電機からの受電回路をすでに設置していますが、発電機はまだ購入していません。

4，5年前の豪雨災害の時は尾道でも断水が続きましたが、我が家ではこの時、水は実家の井戸水で、風呂水は黒色のビニールシートを使って太陽光で温めてしのぎました。

In Japan, where disasters occur frequently, it is necessary to be prepared for any eventuality, such as power outages and water outages.

We have been considering whether to use a generator or a storage battery as an alternative power source during power outages, and we have recently purchased a small portable power supply (2KW rated capacity) battery that can generate 20Wh electricity and store it.

They say that most electrical appliances can be used with this power supplier, but we will test to see what kind of appliances can actually be used and for how long.

We have already installed a power receiving circuit from a generator in our house in addition to the regular power receiving circuit, but we have not purchased a generator yet.

Four or five years ago, when a torrential downpour hit Onomichi, we had our water cut off for a long time. At that time, we used water from my parents' well and heated it for bath water with solar light using a black vinyl sheet.
