Diagram 1 Explanations
10 = Solar Modules (PV)
11 = DC Combiner (Like our MNPV6 or MNPV12 for example)
12 = MNSPD300-DC (Surge protection)
13 = MNSPD300-AC (Surge protection)
14 = MNSPD300-DC (Surge protection)
15 = DC breaker for the Inverter (Also serves as a disconnect for the Inverter)
16 = DC breaker for the PV into the Classic (Also serves as a disconnect for the Classic)
17 = DC breaker for the Battery into the Classic (Also serves as a disconnect for the Classic)
18 = AC L1 Input Bus Bar. (This is where the generator L1 input gets wired)
19 = AC Neutral Bus Bar. (This is where ALL AC Neutrals get wired)
20 = AC L1 Output Bus Bar. (This is where the L1 Output to the Load center for the building would connect)
21 = Battery Positive Bus Bar. (This is where we would wire the Battery positive side of the Classic, as well as
where we would wire up DC loads. Do NOT wire the battery cable to this bus bar).
22 = Earth Ground Bus Bar. (This is the common Earth Ground bus bar where all the grounds get wired back to and
it needs to be connected to the building’s ground rod system )
23 = PV Positive Bus Bar. (This is where the Solar Panels positive lead connects.)
24 = Battery negative Bus Bar. This is where the solar panel negative lead would go as well as the Classics negative
lead and any negatives from the loads. Do NOT connect the battery negative cable to this bus bar
25 = DC Shunt. (The Shunt measures the amperage in or out of the battery. You connect the battery to one side and
everything else to the other side.)
26 = Earth Ground system of the building
27 = Classic Charge controller.
28 = AC Generator
29 = Batteries. (The Voltage must match the voltage of the inverter. Typically 2-3 strings of batteries would be
considered the max.)
30 = Optional Battery temperature sensor. (This is used to compensate for the temperature of the battery. If a battery
is cold it has to be charged to a slightly higher voltage and when it is hot it will be charged to a slightly lower
voltage.)
31 = DC Cables to Inverter
