Still working flawless.

There is other brand (Sure-Start/Eltwin/Hyper Engineering), which will cut the in-rush current by 65% at least. I like this soft-start due to its size (fits in the condenser electrical box) and pricing (about 1/3 less than micro air). I was able to reduce the in-rush current from 152A to 42A...

Your battery pic states: Lithium Iron Phosphate aka LiFePO4. It is recommended NOT to use below 20% of the capacity.

Plus: 24V batteries, cables/wires both (from panels to MPPT and from batteries to inverter), fuses, tools, etc.

Can you provide ball park cost for your suggestion? this will help OP to understand cost wise.

For lead acid battery, you can't use more than 50% of its capacity, unless you want to destroy the battery in short term. So, if your battery is rated 100Ah, then you can use it up to 50Ah. You need to run power audit. In my opinion, your planned system is too small to run your appliances...

Again, what is the refrig operating voltage? If your battery is 12V lead acid, and your inverter is 700Watt Continuous or peak rating? And you want to run 7.2A (assuming 110V refrig) plus others. You will end up kill your batteries and inverter in the short run (if your system even can pick it...

Can you supply the refrig operating voltage and current? this is also to calculate power surge.

Read the below link about cable/wire to use between battery n inverter n fuse/breaker to use.... https://diysolarforum.com/threads/what-wire-gauge-to-use.55666/

All these appliances ratings are not covering power surge. What they have is normal operation rating. What kind of battery is this? LiFePO4? Lead acid? etc? If your appliances utilize 220V, this 12V-100Ah battery won't be enough to handle power surge and normal usage wattage (both refrigerator...

When you purchase an inverter, some inverter suppliers supply cable/wire to be connected from battery terminals to the inverter terminals. Those cables/wires need to be sized correctly or you will end up with fire hazard. Plus, you need to install breaker to prevent from burning the inverter...

You meant by power audit? if yes, go to search box top right corner, and type power audit. You will see lots of topics around it. It will be a good knowledge to know.

I'm talking about wire from battery to inverter in 12V system.

My motivation is for an emergency, especially when the grid is out for over 2 days (in Summer time). I was living in New Orleans for 5 years, got direct hit by hurricane Zeta (2020) and Ida (2021). ROI? when you have no electricity for 9 days...this is priceless... Plus I like to learn/build new...

At the very least, cover the panel with blanket if you plan to do simple and quick fix. Else, have the panel face to ground.
