Unlike residential energy storage systems, whose technical specifications are expressed in kilowatts, utility-scale battery storage is measured in megawatts (1 megawatt = 1,000 kilowatts). A typical residential solar battery will be rated to provide around 5 kilowatts of power. It can store between 10 and 15 kilowatt-hours of usable …
Every day the MPPT starts a new charge cycle. During this it will try to charge the battery up to 14.4V, then switch through absorption down to float, and the battery will remain at the float voltage unless/until there''s enough load to trigger moving back to bulk. If there isn''t enough light, the battery voltage will never reach 14.4V.

Thanks for clarifying Andy. If 192 ohms is the referred load and magnetizing current is negligible, then with no load a * V2 = V1 = 1200 V since the referred load is a²Zl with Zl = infinity. If "magnetizing current is ignored" then no load means no current flow whatsoever. This contradicts the "practical transformer" however.
