Do you mean a charge controller when you refer to 'PWM'??

Reducing power consumption and energy wastage
Richard Mackay replied to Paul Greeff's topic in Energy Use & Conservation
Agreed with water heating via solar bring the best option. As far as the cost of water heating of gas vs grid my understanding is they cost the same. But gas cooking has lots going for it. Battery storage for cooking can't compete presently. -

What are you needing backup power for? Are these devices located in the same area?

Do you use your battery or the grid as a buffer
Richard Mackay replied to Tariq's topic in General Discussion
I presume you are not feeding into the grid? -

Richard Mackay replied to Tariq's topic in General Discussion
The argument I have heard is that the grid is cheaper than using batteries. -
Reducing power consumption and energy wastage
Richard Mackay replied to Paul Greeff's topic in Energy Use & Conservation
What information is available from your inverter? (a list of them provided by the manufacturer would be appreciated!) And how do you read this data (wiring, plugs etc.) -
Reducing power consumption and energy wastage
Richard Mackay replied to Paul Greeff's topic in Energy Use & Conservation
This is my pet subject: the scheduling of RE power. It's not easy to do with intelligent control (i.e by determining the available power and deploying it appropriately) It appears that with inverters that don't have a non essential output it's difficult to determine what the available power is. This puzzles me! -
Reducing power consumption and energy wastage
Richard Mackay replied to Paul Greeff's topic in Energy Use & Conservation
The non essential load supply will switch on when power is available. If you have a lot of PV panels then it can deliver a lot of power. So no need to reduce the size of your element before you see how much power is available. Those without a non essential output reduce their geyser element size so it won't overload the inverter if other loads are also on. -

How can I clean the components inside a Axpert inverter.

Modern electronic components can cope with water but must me dry when you power up..
