Can a 3xaa NiMH battery be charged through a 5V solar panel?

For 3xAA NiMH and a 5V solar panel, you need just a diode, which prevents the batteries from discharging through the solar panel at night. NiMH batteries can be "trickle charged" for long periods of time with little or no damage, but to learn the gory details, consult batteryuniversity.com

What is the input voltage for solar panels?

The input to the circuit can be anywhere between 10 and 40V, which becomes the ideal range for the solar panels. The key features of the IC includes: In order to generate accurate PWMs, the IC includes a precise 5V reference made by using bandgap concept which makes it thermally immune.

How many volts should a solar panel have?

When configuring your array, your Voc should be about 10% below the MPPT input limit to allow for cold temperature voltage increases. An MPPT SCC will convert the solar panel power into battery charge voltage and corresponding amps. 400V at 16A is 6400W. 200V at 32A is 6400W. Same thing.

Does a solar inverter work if a battery is full?

It's not. It's continuous. If your battery is full, the PV is still converted to battery voltage, but the power may go directly into the inverter @ battery voltage to be converted to AC to power loads. It is the Sol-Ark, hybrid, so hopefully it powers load first, then batteries. You must log in or register to reply here.

Another important component of this circuit is the solar cell panel, which should be capable of supplying a voltage of about 5V to 6V with a size of 1W to 2W. It will supply ...

Amps vs volts for charging batteries | DIY Solar Power Forum

Is it better to have 400volts x 16 amps compared to 200 volts x 32amps from the solar panels? Does the inverter even care about the scenario? It barely matters unless long PV wire runs are needed. The higher you get from about 72V, the less efficient MPPT are.

SuperCap

I should work, with that IC or a normal boost to 5V, and an LDO like the MCP1700 to 3.3V, and deepsleep. Add a bulk capacitor in the ESP side, like 100uF, for the short current peaks. You can also monitor the supercap voltage and increase the sleep time when it''s below a threshold.

PWM Solar Battery Charger Circuit

batteries

If your 5V solar charger incorporates a 12V to 5V converter, it will have 90-95% efficiency just like the one above, and negate that point in favor of the 5V battery. If your solar charger uses direct energy transfer (no DC-DC converter) it will have higher efficiency - but may have other disadvantages (too complex to get in to here).
