I am thinking about buying the 400W premium system. Steve from Renogy sent me all the info I need. Thanks!!! He asked me to check the kWhs of the refrigerator. Somewhere around 350kwhs Steve... Will the Premium 400W run this fridge 24 hours? I have a 115ah Vmax battery and a 1000w inverter.

Hello Rob,
I put the numbers in and 400W will run this system. One thing to note is that your battery bank is a little undersized. Ideally, you would want your battery bank to be between 145Ah to 200Ah to run this load. If you run the fridge on your one battery, you will be depleting your battery to a level that will reduce it's lifespan. Additionally, if you decide to increase your battery bank size, it is always recommended that your batteries be as similar as possible. Same model, brand, capacity, voltage, even age are all recommended. So if you upgrade, we recommend you get another 115Ah Vmax.
Hope this answers your questions. I used the US average for sunlight. If you give me your state and zip code, the estimate will be more accurate.

Steve, I am from PA. Do I run my batteries series or parallel? What does that look like?

Rob, Check out this resource. www.trojanbattery.com/tech-support/battery-maintenance/Parallel wiring is what you want. Both positive terminals wired together and both negative terminals wired together. This will keep the system at 12V but add capacity to your battery bank. Renogy Tech Support SR |
