Once your battery is fully charged, very little current is needed to keep it topped up. Most of the available power from your solar panels is wasted as the charge controller is mostly switched off. Enter the 12 volt grid tie inverter which can export all that solar power to your mains electricity grid, saving you money.
But how do you keep your battery topped up and send surplus power to the grid at the same time? The PWM5 Solar Charge Controler from www.256.co.uk is the only charge controller with 12 volt grid tie inverter compatibility built-in.
Make your solar panels really work for you.

Is there a device that can automatically do this function?
Julian i know this was a lot of years ago but can you tell me if there were any drawbacks to using the charge controller and the grid tie inverter on the same panels as shown.This is the only reference i can find on the internet using this method.But it seems an ideal solution to the excess watts problem.I can not figure for the life of me why the charge controller is taking precedence over the grid tie inverter? Until the batteries are charged.
my god that was film so long ago. but still pretty interesting
Doctor Teeth what does being green mean what is the definition of being green mean I'm just curious nobody can ever really give me a actual definition of what that means?
Before declairing something to be green, you need to take into account ALL the energy used to make all the components used.
I'm looking to do the same with my solar array so when my batteries are topped off most of the energy will go to the grid, the problem with this set up is that the inverter will constantly take energy out of the system even when you're trying to put all the energy into the batteries during charging periods
Thanks for the informaive video.
Question: Will the volts of the panels be divided by # of inverters ?
Ex: 30v = 1 Inverter For 2 inverters, volts = 15.
Thanks.
Hello! Have you ever tried – Maxim Earth 4 Energy (just google it)? Ive heard some amazing things about it and my cousin got big returns with it.
cant you wire them in parallel and charge the battery and power the house at the same time
No it's a one way trip into the batteries from the solar panels. I don't take power from the batteries to feed the grid.
Rooftop solar systems don't use batteries. Off grid systems rely on batteries. This is a hybrid system.
Yes
Very clear and informative presentation.
Why can't you use any controller as you are? Seems to me any cheapo charge controller would function similarly, i.e., only draw the current necessary to charge the battery, with the rest of the current going to the GTI.
Nice one exactly what I needed to know. I have both grid tie inverter / charge controller and battery. Was manually switching between battery and tie inverter but see I can now do it this way.
Nice one, can you please show connection that goes to your home? Also if you produce more power than consumed what will happen to the meter?
