Will Solar Keep Me From Melting?

[@seanchoi395]

Hello amazing setup! Quick question, Did you have to ground the panels and have proper conduits? Are they setup in series?

[@ezhasper7069]

Get a soft start from MicroAir!

Random question: How do you run your PV cables to your delta pro?

[@williamsung]

Hey there i a run a solar MC4 10 AWG cable from the panels to a MC4 to xt30 cable.

[@jbrockskill]

@@williamsung I meant like do they go through a window/door/hole cut into wall etc?

[@lukem5962]

How many solar panels do you have connected to each one? Could I run my 4 ton ac unit on and off all day with 5600 watt solar and one battery or would ac drain battery and solar wouldn’t be able to keep up?

[@williamsung]

@@lukem5962 if you could find solar panels to spec out the 5600 I think you could keep the ac running on battery when suns out you’d need maybe 4-5 batteries to keep it on at night I think a 4 ton uses about 3-4 kWh and the blower is an additional 3-500. Depending on how hot and how efficient your line so those are some things to consider.

@@williamsung ok thanks

[@lukem5962]

@@williamsungI could just have one DPU plus 5600 solar and 4 ton should run all day off solar alone?

What are the normal startup watts?

[@TheDutchisGaming]

Since the terminology is all over the place. Does it use 5kWh (amount of energy) to boot up? Or does it need 5kW (energy used per second j/s) just to run?

[@jackwilson9829]

Electrician here, does not need 5kwh to start, electric motors can use up to 4x rated current to start up but its only for a few seconds at most. Also this is a split system so the compressor wouldnt be using all 5kw probably more like 2.5-3.5kw which would give a max startup load of 14kw. Side note, the array is unlikely to be able to output what which would just mean the motor would start abit slower

[@williamsung]

So the power draw for boot up was around 40 amps at the 240 (I do have a soft start) so the initial draw was probably in the the 8-9kw range and drew a constant 4-5kw with the blower running as well. Inverters and battery powered the inrush

@@williamsunghow long does your 5 ton ac unit last with solar and batteries and also just batteries at night?

[@steves1390]

Going the mini split route if mine craps out

[@williamsung]

I am also strongly considering doing the same. the ducting going all over the attic and still not having good ventilation is nuts to me. And so expensive to maintain😅

[@JoshW1ck]

So it weighs 5000kg's? Who would have thought 🙈

[@dannypierce1426]

How many do you have because it says it will only do a 3 ton air conditioner if you have one of them so you must have two of them

[@williamsung]

@@dannypierce1426 yes and it will depend on the start up amps which you can lower by using a soft start and with it you can start up even some 4ton acs with one☺️
