Battery charge/discharge function test

The battery function test checks that a connected battery accepts charge and delivers discharge on command. The inverter runs a separate charging test and a separate discharging test. On some hybrid inverters, you start the test in the battery configuration step of the installation wizard with the Charge battery and Discharge battery buttons. The test needs a suitable state of charge. A nearly full battery cannot be test-charged and a nearly empty battery cannot be test-discharged, so pick the test the battery can actually do. The inverter logs whether each test passed or failed. If a test fails, check how the battery is installed and run the test that has not yet been done. Even if a test is reported as unsuccessful, finish the installation wizard as usual. Some home hub systems have a battery self test under the maintenance diagnostics menu. It checks communications, charging and discharging, and saves past results for review. At large storage commissioning, a balancing test is run in both the charge and discharge directions after a manual discharge at rated power. Do not move on with the test plan unless these tests pass.

<!-- review notes

• sentence 1: support check: partial - Separate charging and discharging tests exist, but the passages never say the test checks that the battery accepts charge and delivers discharge on command; that purpose is inferred.
• sentence 6: support check: partial - The Home Hub self test under Maintenance > Diagnostics verifies communications, charge and discharge, and lets you view past results; 'saves past results' is implied, and 'some home hub systems' is a framing not in the passages.
• sentence 7: support check: partial - Passages state discharge to 0 by manual command at rated power, balancing test in both directions, and not moving forward unless all tests pass; they do not mention 'large storage commissioning' explicitly.
• sentence 7: review: partial - Powin secs 8.6/10.0 support a balancing test in both directions after a manual discharge to 0 at rated power, and say not to move the test plan forward unless all tests pass, but the 'large storage commissioning' scope is not… -->
