Hello Jerry and Martha, it depends on the sun you have but if that is good generally a 150w panel and a couple of batteries will keep up with low energy lighting, charging your phones, a bit of laptop use and a little TV nothing more. If you are running a microwave, fridge, leaving your inverter on all the time then you need to spec up a lot! If…[Read more]
@flyingppg I guess your little camper suits you fine.
But me and the others here prefer to use free power from the sun instead of generators which need gas or burning costly propane.
How much juice does a TV use per hour? Microwave? Electric appliances Computer? My lifestyle is very comfy and lacks of little.
Maybe you don’t use any of those,…[Read more]
Hello Jeff, that’s insane! Did you ever find out why your charge controller was struggling to find it’s maximum power point and running up and down the VI curve all the while? Didn’t seem right to me. Nice off road electric bikes too! It’s rare to see even a single large 60 element panel on a vehicle over here. You’re all doing solar on a…[Read more]
Hello Eddie and Eileen, 1500 watts! Maybe 6 x 250 watt panels, that’s 5m x 2m of clear roof space just to fit the panels? What batteries do you have? I don’t use power like that at home. What are you driving, must be a bus? What are you powering, must be a steel foundry?
We’re planning on joining you next year from about M…[Read more]

The Mppt charge controller I have (epever tracer 3210an) operates in pwm mode when the light is low and only switches to run the charging through the dc-dc power converter when it decides there is a benefit to doing so. The stats you can collect on your PC are also very cool.
I’m not a fan of lithium as a habitation battery. Check they h…[Read more]
Jeepers Doug, what are you wanting to power with that 800-900w of power on your roof? Blackpool illuminations? Given you sound unsure have you calculated the power you actually need? No point in over doing it. But that said you Americans do do everything much bigger over there.
Without question, if they will fit, go with the 300w panels. They…[Read more]

Hi, the problem in your system, and from what I read in most of the starter kits on the market, is your charge controller. You are using a PWM charge controller which is very inefficient. You may be throwing away 20-30% of your power with that charge controller, almost a whole panel, and making them run hotter too which increases the losses…[Read more]
