If I get the 2000 watt inverter, how much wattage in solar?
Hi rocelp and welcome to the forum. Glad your eager and asking questions to figure out to do before you drop a bunch of cash on something that isn't going to work.
You need to slow down a little bit and evaluate how and what you are trying to do. You are not going to run a 2000w inverter from a 70AH battery bank for more than few seconds at any kind of load. A 2000w inverter is only really needed if you are planning on running a microwave from it which is going to require a large battery bank (like 4 6v batteries at a combined 450 AH and then it will only do it for a few minutes)
Everybodies systems are different to meet different needs so there is no generic specific right answer that works no matter what. However IMHO a good starting point goes something like this for any extended boondocking/drycamping events
- 2 6v Golf Cart Batteries, about 225 AHs
- a good quality 1000w to 2000w generator. This can power your converter for charging the battery bank and running the Microwave, if you want AirCond then you need 4000w generator
- a good quality converter (35 amp model if using 1000W generator, 50 or 60 amp model if using 2000w generator)
- If you don't like running the generator just to charge batteries or want to limit generator to high power 110v systems then use a solar system to charge batteries. A good starting point is approximately the same wattage solar as AH battey bank and then adjust up as needed based on experience (I started with 125 watt solar and have moved to 265 watt solar with dual 6volts)
- A 300 watt PSW inverter will provide the power you need for TV, laptops and charging cellphones&etc (I actually have a 600W inverter with remote control and can power several TVs and laptops at the same time)
So based on your description and it is my interrupation only, you need the following as a starting point:
- 35 Amp PD converter with charge wizard
- Honde EU1000
- Dual 6volt battery bank
- 300watt PSW inverter
- 200 Watts solar
