Hi! First you need to have an idea of the total watts ng balak mong ikabit... and then, how long mo balak gamitin. For you to know if enough ba yung power supply mo. Computation: Total capacity of the power supply divided by / Total Watts of the appliances = Average Hours the power supply will last. The numbers won't lie. Of course there are other factors that will affect your consumption, like ang load ng ref mo, the weather (ref and AC will work harder during summer) but at least you'll know the average. With your planned load, the minimum capacity you need is the 3500wh OCPH Powerhouse + inverter. Anything smaller and you'll use it up in a couple of hours, since you have a portable AC. For more questions, just visit us on FB and send a message. facebook.com/ocphpowerhouse Thanks for watching!

Thanks Sir Charlie!

Hi! The OCPH Powerhouse units are huge capacity power supplies. 1600wh and 3500wh. Charging through DCDC is only meant to replenish the battery a bit habang bumabiyahe, but not fully charge. That only works for small capacity units.
