I understand that you are working to a budget. My recommendation remains the same . Work out your power requirements and then price a system to meet the demand needed. If not within budget you will be in a much better position to decide if any piece of electrical appliance can be excluded from the system.

That’s definitely not my strategy that’s why I started this thread.Which is why I’m looking for more battery power as you say 100Ah is on the limit. i will try to work this out fridge 130w x10 hour. 1.3 kwh fanx2 80wx8 hour. 640w blender 400w x1hour. 400w stereo 45w x8hour. 360w total. 2.7kw is that right where do I go from here Link to comment Share on other sites More sharing options...

You probably want to store about your daily usage (although a lot of the use will be during daylight as I see no lighting ) in order to bridge those dull days. 2.7kWh @ 24V = 112Ahr look at 140Ahr so you don't go below 80% discharge (assuming LiFePO batteries like you show above). A 300W panel will generate about 1kWh per day so 4 panels with an MPPT charge controller. 1200W charging @ 24V = 50A so look at a >60A controller. In reality you'll probably be able to run the fridge over night on that as it won't be consuming the full 130W at all times, just how much less depends upon the weather, the fridge and it's positioning (shady?). Add a 1500W pure-sine inverter and you're good to go. With anything solar, bigger is always better so a bigger battery, charge controller or more panels can't hurt. 1 Link to comment Share on other sites More sharing options...
