You can use this watt meter. It is for DC circuit. It show watt, kwh, A, voltage, peak volt/watt/A. A very usefull to monitor the uasage. Specially for solar.

UPS have capacity size. Depend your requirement usage. It actually is the inverter size. Battery size in the UPS is for how long it can backup.

Hi Ozak,

Have your grid tie inverter gives you any problem?
I'm interested in getting one, but worry about its reliability & safety.

No problem. I have 12v and 24v. 24v give higher yield. Have run for more than 6 month.

But I stop using now. As it bit boring for just return back to grid.  Now running off grid.

Have plan to redesign to combine the off grid and grid together.

Thanks for your feedback.

Btw, what kind of battery you are using for your off grid system? SLA?
