hoi, i read this in this 70pages lol: SOL mode is for on-grid use as a solar UPS. It will not use the battery at all, keeping it fully charged, until you lose both solar and grid at the same time. It will reduce but not minimise grid usage. It will maximise the life of a lead-acid battery. Not so go...

btw , some pictures of the installation :

THX Coulomb for the time and the info!!!

i have set "back to battery mode" = full

because if i read it right , when the solarpanels are connected it will not be activated that much (hope not)
full = bulk = 57.4v

What is the meaning of "Back to Battery" on the pip4048 ? for now there are no solarpanels connected to my installation, so it runs on battery power till "it's out" and than it reloads on gridpower ... till 55v (back to battery), with 60A ( i know it's stupid*, but thats the way till i have installe...

every panel is VOC : 65v and 6.58A Isc (333wp) You have not stated what the Vmppt voltage or Imppt current is. I'll guess the Imppt at 6.0 A; in that case the Vmppt is 333/6 = 55.5 V. This is less than the battery voltage at the end of bulk charging. You need at least 1 V more than the battery volt...

hoi, I have an other question, what would be beter for the pip4048MSD? you can have 145v VOC and 60A max input current, so 2 panels in serial and than 4 parallel? (130v / 26A) or all in parallel? every panel is VOC : 65v and 6.58A Isc (333wp) (8 panels on one string, i have 2 string inputs and so i ...

okidokie coulomb, thats as clear as it can be
thanks for the post! i will not try to "downgrade" to yours, hope that the "acid bug" is not for my version...

hoi, i'am new here (from belgium , new to off-grid) and have read almost the 60pages, what is intressting is the acid new firmware.. but i have a problem (i think) my inverter (pip4048MSD , mppsolar): http://kg666.org/pip/pip1.jpg my inverter is from 2016-04 i think this is my firmware (yes?): http:...
