Slowpoke

It is all about fooling the grid tied inverters thinking that the grid is still working. Then it will produce power. Can anyone recommend a watt meter for the whole system? I have Dlink smartplugs for my mining rigs that show the power usage on the plug. I want something like that for the whole system. Something stupid that display only. So that I can put it where the guys in the workshop can see it and know their power usage and not trip the inverter with over usage.

I have replaced the 2 Axpert inverters with one SOL-I-IS-5M. I send the Axpert ones back this morning with the same courier that delivered them. If the grid go down then I will have one inverter running from solar. The idea is to unplug one Omnipower grid tied inverter and plug this one in. In a few months or more I will replace the other Omnipower with a SOL-I-IS-5M. In true space kadet form I think the one SOL-I-IS-5M will start the Omnipower inverter. I do not think it will be wise to do that because what will happen with the excess power if I do not use it. Last December it produced about 45 to 54kWh per day. The monthly yield is 816.5kWh up to now. Any suggestions would be welcome.

Hi plonkster, Lets go with option 2. What is the minimum battery bank that I will need? Do I need to change the solar panel setup from the 2 x OGT5.0-1P to work with the Axperts? . I have been reading up on the setup and have confused myself over the weekend. Why do you have a Commodore 64 badge? The Commodore 64 were one of the first computers I ever worked on.

Hi, I need some recommendations. A year ago, I installed 30 x 280W solar panels with 2 x OGT5.0-1P grid tied inverters. It seemed like a good Idea at the time. It produces more than enough power during the day but the moment the grid goes down so does the inverters. Currently our municipality is in arrears with Eskom and we are getting daily power cuts. I have a small 3kva Axpert inverter with 4 x 100Ah batteries that is now 3 years old that I use for essential necessary systems. I have a LPG gas powered generator for rainy days. I can not run other devices until I start the generator. I got 4 x 100Ah batteries two weeks ago with the idea that I want to connect a second Axpert inverter for my crypto mining machines. Not done yet. Now with this municipality throwing a spanner into the works I have ordered 2 x Axpert 5kva inverters to replace the Omnipower ones as they are the cheapest. I am going to setup them in parallel. If the municipality do not come to agreement with Eskom in the next week we will have power cuts from 6 am until 8pm. As a small computer retail store owner, I am not worried about power after hours. I would like to do AC coupling and use the 2 x OGT5.0-1P to produce AC power for the inverters if possible. The plans were to replace them in another 2 years with a full hybrid system. The question is what is the minimum battery bank that I can get away with? I plan to replace it with lithium in the future and go off grid completely. How will I direct the electrician to install the system? Minimum system requirements without compromising safety.
