Eto ang pangalawang parte ng pro series tutorial ko na “Circuit Breaker Calculation for Solar PV System Pro Series Tutorial.” Alinsunod po eto sa PEC 2017 at NEC 2020… kung paano magkalkula ng amp rating mula sa Solar Charge Controller o Hybrid Inverter. Maari din po na mai-apply ang kalkulasyon neto para sa pure off-grid inverter.
PAALALA! Huwag kaagad-agad magtanong sa comment section ng hindi pinanood ng buo ang video tutorial.
I always say this to all participants of my Solar PV webinar & seminar... "An overrated overcurrent protection device (circuit breaker) is far more dangerous than an underrated one."

Tama po si sir kahit tama ang kalkulasyon iinit ang mcb kung iinit ang mcb makikikain yung mcb sa capacity ng battery Ako nagtipid gumamit ng mcb pero nung uminit napilitan ako na palitan ng mccb ayun doble gastos

Thanks a lot again sir. I learnt a lot from the video and today, there's automatic caption in English. It didn't work perfectly but appreciate the effort. I think I got almost everything from the onscreen displays. Concerning the SCC rated at 60A and 3200W but connected to only 2000Wp solar panels, will it still be OK to use an MCB rated based on the SCC's maximum rated capacity (i.e. 60A,3200W in this example) if the cables are selected to handle the maximum current? So that if there's need for expanding the solar panels to the maximum power of 3200W, no change of cables and MCB will be necessary.

Hello Sir JF. may nakita ako ibang tutorial dito sa youtube sa pagkuha ng CB size ng Hybrid Inverter to Battery Bank ang ginamit is Max PV input Power/ System Voltage. Kung i-aapply sa example nyo 6500W / 48V = 135.4 A So gagamitin is 150A CB since eto pinaka malapit .Ano masasabi nyo dito sir?

@SeanRaynon 6 ай бұрын

Bravo! Excellent tutorial sir. Speaking of Max Charging Current (Hybrid Deye 5kw) and max capability ay 120A ~ mi advantage ba if I set it to LOWER value. For example, my Max Charging Current is 80A and my Max Discharge Current is 80A. At ano po and disadvantage if I use the above lower values. Thanks.

@JFLegaspi 6 ай бұрын

Ano ang dahilan kung bakit ibaba ang charging current? Required ba ng BMS rating ng battery o C-rate ng battery?

Please make a review for this Hybrid Inverter. and here is the Data

@JFLegaspi 5 ай бұрын

Yes you need to install DC circuit breaker between solar panels (PV array) and hybrid inverter (MPPT input), then AC circuit breaker for the hybrid inverter's AC output.
