Switch between Grid power and Solar power AND use grid backup

One of these two systems is backed up by the utility and the other by a generator. My question is basically the same for both utility and generator backup power. 1. I run in SBU priority. 2. When the batteries are low, I want the utility/gen to charge them as well as supply loads (especially in the case of the generator version). 3. I want to

Power supply reverse shorted? It might not be toast...

When this happened to me, sparks flew and subsequently the power supply stopped working correctly - acting shorted, dials wouldn''t produce intended changes on display, and negative voltage was produced from the terminals. I wanted to post here and share that (at least in my case) it was a fairly easy fix.

PWM solar charge controllers: A quick and thorough explanation

When the PWM controller is ON, the solar panels are connected to the battery; when OFF, the solar panels are disconnected. The period of time for which the solar panels are connected is called Duty Cycle. The longer the duty cycle, the higher the power delivered to the battery. The length of this duty cycle depends on the battery''s state of

5 Reasons Your Inverter is Not Charging the Battery

A solution for low battery voltage is to charge it with solar power, and when there is enough power, hook the battery up to the inverter. For this to work, the solar panels must be the right size to charge the battery bank. Whether you opt for a solar panel or another power source, the important thing is to supply the battery with power. Doing

6 FAQs about [Solar power supply is connected in reverse and charging does not light up]

Why is my solar battery not charging?

This is especially evident when DC loads are not drawing power from the battery. It is important to note that this behaviour is normal and not a fault. To determine the battery's state of charge (SoC), check the battery monitor (if available) or inspect the charge stage indicated by the solar charger.

Why does my solar charger only show voltage and power readings?

If the solar charger only shows voltage readings and omits current and power readings, it indicates that the current monitoring is bypassed due to a potential PV negative being mistakenly connected to the battery negative. To rectify this, make sure to connect the PV negative to its respective terminal instead of the battery negative. 8.11.2.

What happens if a solar charger is unable to turn off?

If the solar charger is unable to turn off the PV input, it will go into a safe mode in order to protect the battery from over-charging or having a high voltage on the battery terminals. In order to do that, the solar charger will stop charging and disconnect its own output. The solar charger will become faulty. 8.12.12.

Why is my solar charger not resetting?

Disconnect all wires and then reconnect all wires to force the solar charger to restart. Also, make sure the minus on the solar charger (PV negative and battery negative) is not bypassing the solar charger. This error will not auto-reset. If the error remains, please contact your dealer or distributor, as there might be a hardware defect. 8.12.7.

Why does my solar charger omit current & power readings?

This only applies to some 10A and 15A solar charger models. If the solar charger only shows voltage readings and omits current and power readings, it indicates that the current monitoring is bypassed due to a potential PV negative being mistakenly connected to the battery negative.

What happens if a solar charger is moved from 24V to 12V?

However, if the solar charger is moved from a 24V system to a 12V system, it may not recognise the system change. Consequently, it will continue charging with 24V battery charge voltages, while the connected battery is a 12V battery, leading to overcharging of the 12V battery.
