Still happening, did not find a solution.

I hope someone can assist me. The battery SOC is not displaying on the graph. Is there a setting of way to get it to display. When I go into the devices section graph it does display but would like it to also show on the landing page. The latter for some reason does not show the load again.

Here is a similar product although at a much higher price. Does not seem to cover LiFePo4 https://www.4x4andmore.co.za/products/20-amp-dual-purpose-dc-to-dc-charger-with-mppt?variant=50192571654&currency=ZAR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOopSZtKsx0mtAuV36YF4fNPVOVRd_4Zzma09iU6tgZku9fe_Om1OAO8

Had it for about a year now and not really used it. Need to make a plan

Yes, not that I understand how it can't convert batteries 50V to 230V but can still convert the solar voltage to 230V?

It is possible to remove it temporary, but who can repair it?

A few weeks ago we had lightning. At first I thought nothing was damaged, but now I don't have backup power anymore. The batteries charged to 100% and now they stay there. I have restarted or rebooted everything. Reran the PV master setup to make sure about the usage setting (General). The batteries measure correct voltage and all lights are fine. The inverter runs fine from solar power and grid power. Just don't seem to use batteries at all. When I disconnect solar and grid everything shuts down even though the batteries give voltage to the inverter. The system is a Goodwe 4.8 (ES) Batteries Pylontech 3000 3.5kWh - 2off JA solar panels 3.8kW Any suggestions? I suspect the inverter has got some damage and these are not supported anymore thus it would imply a new inverter.

This thread is specific to Sonoff and geysers. With the POW range of sonoff you can measure power usage of the geyser but it does not work if you use a relay. With the POW sonoff switches you can set a current limit so if you get a element shorting then it can switch off without damage. On the POWR2 the 15A rating seems too close thus hoping the 20A rating of the POWR3 is enough.

OK so the second one lasted me a bit more than a year now. Next up I am trying the improver 20A version. https://www.robofactory.co.za/smart-switches/497-sonoff-pow-20a-elite-smart-power-meter-switch.html

I vaguely remember studies that scaling actually increased the efficiency of a heating element due to the larger surface area. Up to a point and not applicable to boilers etc.

Under correction but I think the breaker for your secondary board should not be connected via the earth leakage. You should have another earth leakage device in the secondary board for the plug circuit.

Few things to ponder: Normally a cable supply from one to another DB is SWA (Armoured cable). Don't know what the legalities are about running wiring in conduits. Electrician should be able to give you answers. Current carrying capacity should not be a problem. 2.5 I think can carry 20A. Voltage drop as mentioned above would be an issue and requires a thicker cable as mentioned. Fault currents to be kept in mind. Cascading of breakers. Get an expert to check. If your earth leakage trip then the breaker is most likely in the wrong position in the board. Get someone in the know to check. Maybe it is an option to install a lights and plugs breaker in the main house DB and run twin and earth in conduit for each to the flat bypassing the DB in the flat. Someone in the know can comment.

Portable aircons sucks. The suck the cold air from your room to cool the condensing side and that brings efficiency down. If you have a two pipe unit or can connect the condensing inlet to suck air from outside you can double the efficiency of the unit.

What does a 300MH/s rig cost nowadays? From your graphs it looks like the rig use about 750W of power. Is this correct?

Do places like Makro etc use this micro grid systems? Where can I see more of how it works?
