Sɛ́ ebia wɔreyɛ instɔlehyɛn a ɛwɔ hɔ dedaw no foforo anaasɛ wɔreyɛ substation foforo ho nhyehyɛe no, DFUN boa nnwumakuw a wɔde di dwuma no ma wohu asiane ahorow a ɛwɔ batere mu ntɛm, ɛtew nsiesie ho ka so, na ɛma ahoɔden a wɔde si hɔ dedaw no ahotoso tu mpɔn.

Nsɛm a Wɔtaa Bisa

So wobetumi de batere a wɔde hwɛ nneɛma so ahyɛ mu a wɔrento substation no mu?

Wɔ nnwuma dodow no ara mu no, wobetumi de nhyehyɛe a wɔde hwɛ nneɛma so no ahyɛ mu bere a wɔtew ɔhaw a ɛba adwumayɛ a ɛwɔ hɔ dedaw no so no so. Ɛsɛ sɛ nhyehyɛe a wɔde besisi hɔ no di anyinam ahoɔden ahobammɔ ho nhyehyɛe pɔtee a ɛfa beae pɔtee bi ho akyi.

So nhyehyɛe biako betumi ahwɛ Ni-Cd ne VRLA batere nyinaa so?

Aane. Battery monitoring platform a ɛyɛ adwumaden betumi aboa battery chemistries pii, a Ni-Cd, VRLA, VLA, ne lithium battery ka ho.

So batere a wɔhwɛ so wɔ Intanɛt so besi tumi a wɔsɔ hwɛ ananmu?

Dabi, Intanɛt so nhwehwɛmu ma kɔkɔbɔ a ɛkɔ so ntɛm, bere a tumi a wɔsɔ hwɛ bere ne bere mu no hwɛ sɛ tumi a wɔde sie ankasa ne bere a wɔde yɛ adwuma no yɛ nokware. Sɛ wode abien no nyinaa di dwuma a, ɛma wunya batere akwahosan ho nsɛm a edi mũ kɛse.

Ɔkwan bɛn so na nhyehyɛe no tew atoro kɔkɔbɔ so?
