HI - I'm in the beginning stages of spec'ing, purchasing, installing, commissioning, etc. a hybrid solar pv system for my 2-level house here in western North Carolina.
Current/Future Goals:
1. current - battery power backup for critical loads (240V well pump, 240V water heater, 240V central heat, 120V refrigerator, 'select' upstairs/downstairs 120V lighting/wall outlets
2. future - reduction in power bills (via multiple strings of solar panels, load shedding, power shedding, smart load, net metering agreement with utility)
To date I've invested in (1) 18kPV Hybrid Inverter, (1) conduit box, (1) EG4 wallmount indoor battery, and (10) 400W solar panels. I initially will install the inverter and battery for use as critical loads backup. The solar panels will install later.
Question:
I'm reviewing EG4 literature '18kPV 1Line Diagram - v1.3' and evaluating which design options best suits my current & future goals.
In above document under notes for 'Critical Loads Panel' there is a note to 'Refer to EG4 Design Guides for discussion of partial home and whole home backup'. I can't seem to locate any EG4 'Design Guides' about this, so if you know what they're talking about please let me know
I'd love to read it. (I sent EG4 an email requesting this same info, no reply back yet).
Thanks in advance for any feedback!
