I have a Meanwell 20 amp 5 volt power supply directly off main busbars supplying an old router on DRT and 2 Raspberry's running Solar-assistant and Node Red. Have a mini inverter above the 18Kpv (750 watt) spinning a small recirc pump recirculating water thru an electric tankless and then thru...

I would guess they could tell if you sold back more than your production/battery size in a given night? Also the 18Kpv has been on the CEC list as an inverter for 6 months now, but not all the boxes have been checked (CRD-PCS functionality among others)

I have found that PG&E has their own list of equipment/requirements and the CEC list is the minimum. The only way to see the PG&E list is during the application process. The 18kpv is now on the PG&E list of inverters for grid tied without a battery? (maybe < 10 KWh battery size i think) but...

City of Fremont actually has a app to report building code violations for your phone anonymously .... how well do you get along with your neighbors??

Little did I know... Latest in the saga with PG&E. i screwed up the first application (applied in wrong category) so they kept my money and cancelled my application. I reapplied with same drawings documents and now they demand the following: CRD-PCS Capability – Battery inverter must be...

Given you are using the same brand of panels with same Voc with double or 1/2 the amperage rating indicates that it is likely these are all built from the SAME cells or at least very similar so, that series/parallel arrangement you are using is probably identical to the series parallel...

I'm in the same boat, tankless gas and some excess pv i need to use up. Dougbert, do you find the gas tankless shuts down if the feed h20 temp is above 95F? My tankless claims to shutdown with too high of inlet temp.

forgot to ask, are the arrays pointed in different directions?

Um, 8s2p is 16 panels, he has 10. whats wrong with 10s1p? 586v at -30F, dont know your lowest ASHRE temp tho? also 10s1p will start producing a little earlier in the morning,save wire and save your MPPT's (assuming you have further plans?)max Vmp at 410v well under eg4 mppt max of 500...

Here is the program in all its glory: Today the Environmental Protection Agency (EPA) announced the Solar for All competition, which will award up to 60 grants to states, territories, tribal governments, municipalities, and eligible nonprofits to create and expand solar programs for low-income...

other side of terminal

These are my cables from EG4 for my powerpro batteries. thats a 2/0 cable

power wall rated 11.5 kW AC of continuous power per unit

if they are color coded then ground one of the unconnected conductors to the ground wire (you did run a ground wire?) then check other end with ohmmeter
