Hi, new here, I`m trying to come up with a decent package to run my Two refrigerators and a Freezer chest.
One of the refrigerators pretty new not even a year-old, runs at 5 amps 120v (that`s on the door decal), that gives about 600watts.
The other refrigerator is about 15 years old, NO STICKER, but I assume it pulls more power, being that old.
The freezer chest I assume it pulls half of what the refrigerator uses.
I know that start up watts are to be taken into consideration, so I`m going with at least 2500 watts for all 3, I`m I being too conservative or realistic about that number?
I purchased a Killawatt meter from Amazon to measure the equipment, it arrives tomorrow, but I was wondering if my estimates are somehow correct.
Planning to use a 3000-or 3500watt inverter with 4 12-volt 200ah LifePo4 plus batteries, (don`t know if it`s enough batteries) I was told in another forum to use a 48-volt setup which is better.
So, wiring the 4 batteries in series to get 48 volts will keep me at 200ah.
Question is, Is that enough to get those 3 fridges running all day and night in a 24 hour period, (of course it will be cooler and the doors will not be opening as much during the night, plus the freezer chest usually stays shut most of the time). I don`t know the exact number of surge watts all 3 consume, but I was wondering if someone has an idea of what to look into, plus I assume the solar panels will also be providing consumable power during the day on top of charging the batteries, also how many solar panels to charge those batteries in one day with about 5 hours of direct sunlight, plus some extra wattage to run the loads during the day, I`m planning to get t least 16 100 watt panels, (don`t know if enough) wired to supply the 48 volts with a MPPT Renogy 60 amp controller that can do 12V 24V 36V and 48V. I can put the controller pretty close to the batteries, about 4 feet.
The newer refrigerator will be about 45 feet from the inverter and the older refrigerator with the freezer chest will be next to each other no more than 25 feet from the inverter. This is already the 120v ac side, don`t know if I loose too much with the loads too far from the inverter using extension cords.
Also, there are not many choices for a 48volt dc to 120v ac 3500 inverters out there, planning to NOT hook it to a generator or to the power grid, just plug the refrigerators and chest cooler with extension cords from the inverter, unless I can wire a little breaker box to the inverter with 3 breakers for the 3 loads, then hook extension to them.
What inverter you guys recommend?
Thanks for your responses in advance.
