Thanks for the info. Your setup is connected to grid? My manual want breaker and surge protection on the IN power sources, grid and pw. Pink

This one ok for ac? Pink

There is 2 single serial strings who have its own pw port on inverter. So i will use a dc breaker and dc surge/lightning protector between panels and inverter. AC anti surge/lightning protector i should use for grip power before inverter? Pink

Thanks for that info Pink

From Inverter manual: WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable: single crystalline and poly crystalline with class A-rated and CIGS modules. To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When using CIGS modules, please be sure NO grounding. Means ? Pink

Any one have some good suggestions for this parts? Price vice Im looking for something midrange i guess. 2 x 600VDC/30A circuit breaker 2 surge protection 1 x AC breaker (32A?) Pink

regarding: surge/lightning protection: I have 2 serial strings so i guess i need 1 unit per string then?

Here is a nice deal from same company Pink

what wire u suggest for serial string panels? Pink

Thanks for the input. what i estimated was production/hour ( watthour) to see what would be capacity left for charge batteries. Pink

Tried another calculation to see what battery/charger i can handle with the setup: Production estimate: 330w x 20 x 0.8 is estimated average around 5300wh Usage estimate: 1000kw/month around 1500wh Left production for charge: 5300wh - 1500wh = 3800 wh Daily production capacity for charge : 3800wh x 5 hours/day =19kw Charge capacity: 3800wh equals 79A 48v Battery capacity volume: 24kw x 80% usable = 19.2kw Battery capacity amp: 500amph/48v maybe not a common size so might go with 400amp. If i got something wrong pls let me know Pink

Your right thanks.. i was writing A instead of wats..i will need a max of 20kw/day from batteries. 80-90 % was better, Pink

UPDATED PLAN: After some more discussions and info here in the forum i did some changes on the plan: I called Global and ordered 9 more of the 330w panels, so i will have a final setup with 330 x 10 panels x2. Most probably with 2 x 5xxx kw in parallel. The final setup the would need around 800A batteries (400A usable) Here is something not clear for me: When parallel 2 inverter i see the illustrations show AC IN shared too the 2 inverters and AC OUT combined to load. What do i need for this to get them secured shared/combined? Can the 2 x AC OUT be combined together in the breaker box? Pink

Thanks for that info.. I change the plan to 10 panels on the inverter. How you pull this data from your system? you use phone or pc? Pink

The 5kW MPP have a lover limit of max solar voltage (450v) Btw i just noticed the VDC was discussed in the old tread and was said to be 45voc but its 45.5voc. So 500.5vdc with a max 500VDC inverter ?? Pink

Yes, i just did a basic calculation: Mpp: 125A x 6 hours converted to watt: Just over 15KW 2 x Easun: 2 x 100A x 6 hours to watt; Just over 26Kw Pink

Well im not sure at all about that much storage.. Thats why step1 and 2 is just solar and grid first, then step 2 batteries who match the current panels capacity. maybe 12kw or something? from 12kw i should get 6kw usable power? I dont need to get 100% power from solar, just want to try figure out a estimate for future setup to ad up with what i buy now. Pink

You have some good points there. If i get the MAX series 8KW 48Vdc : current solar panels: 330 x 11 = 3630 Then if future solar panels same : 330 x 11 = 3630 And my daily usage is average 35kw. The charger is 120A. So if i have 6 solar hours per day i would need around 75% of my usage in usable battery power? 25kw or so.. 120A charger handle that? Pink

Yes i guess thats the smartest to do.. Whats your view on mpp solar 8kv vs 2 x5.6kw easun? Pink

Got my panels today delivered from Global and all looked good. Still thinking what inverter to go for. Last days i see there is a new Easun/Powland 5.6KW hybrid inverter at 17300TB with wifi and Parallel. The Mppsolar 8kv is now USD 1210 + some watt. From what i have read its migh not very much difference between Mpp solar units and Powmr, easun, powland etc. ( i readed they all made by same company) Pink

Thanks for that info.. It should be near 50% of my usage then. I use 1000 unit per month, or 33kw per day Pink

It was a local offer they was selling out some stock, it was less than 20 panels before i got my 11 panels. Im very happy with the deal.. Pink

Panels ordered today so now i started a new tread for the project here Pink

After some long research it was time to get this solar project started. Today i ordered 11x 330 Sunergy Poly at B2990. I could not resist this offer, best deal i see in long time, Waiting for delivery tomorrow. Pink

You have separate busbars for the solar breakers?
