Hi! I had a relatively close lightning strike this weekend, I lost some network equipment and a 3d printer. My Inverter (Goodwe 5048ES) at first glance survived. It charged the batteries fine from the solar panels the day after: But this graph shows the issue: I'm not getting anything out of the batteries since the strike at 20:30. Looking at pv master's alarms I get this (sometimes?): "Discharge current limited by bms is low" sounds like what I am experiencing. SelfUseOff - No idea why I'd be getting this, my mode is set to general/normal. I don't even know where to set the times. When I go back to basic setup and set mode to normal again the alarms are seemingly reset. Maybe I'll get this again after it ran for 24 hours and it made a realization... SOC Delta OverRange - That doesn't sound good. Here is the parameters info from PV Master: The CT meter tests says it is connected correctly. I shut down my batteries and started them up again. I guess I should do the same with the inverter, I thought if it can charge it can discharge ... Any ideas ? Thanks!

In my case my 2kw geyser was already using free solar energy. I thought I'd give my inverter a break, which I am, I'm not exporting power to the grid like in my graph anymore due to my prepaid meter running forward whether I buy or sell. I spent R25k + 1k a year to have an additional piece of equipment that can break. The only benefit is that I can wash dishes at 9am instead of 12am. In terms of ROI, it will never pay itself back. Sound like a bigger heat pump will solve the original poster's problems though...

I just had an ITS heat pump installed. The 5kw Super (1.25kw usage). Here are my thoughts. I have 4.8kw of solar panels, a 4.6kw goodwe inverter and 7kw of lithium batteries. Before my heat pump upgrade I had a 2kw element in my 200L kwikot. I'm still not sure I should have bought the heat pump, the 2kw element took +-2.5 hours in the morning to heat up the geyser, so 5.0kw, where this does it in 1 hour for about 1.6kw. I've also had my geyser replaced with a more efficient one, so maybe the water is just hotter in the morning anyway. The heat pump is one extra thing that can break and R1000 a year for a mandatory warranty tied maintenance checkup. R25,000 for the unit with installation. The only benefit to me is having warmer water faster in the mornings and maybe putting away more energy into my battery banks on a cloudy day. I doubt I would buy one again (Solar water geyser was out due to placement and orientation), haven't lived with long enough to decide yet... This is the ITS's power usage in the morning. It starts off at 9am with +- its rated 1.25kw but there is a huge spike at the end of its cycle. Anyone else seeing this ? Here is my previous 2kw kwikot running on a good day from 11:30 to +- 2pm

Hi! How high does the inverter and switches need to be off the ground to pass a CoC? This is in my garage, but I guess that is irrelevant. If they are too low what would be the easiest solution to rectify the matter ? Would I just need to move up the AC side ? Would a lock box of some sort fit over them ? Thanks!
