Increase wood stove efficiency during blackout

When the coals burn down and there are no blue lights, I close the damper on the chimney almost completely; the coals will continue to heat for a long time. The large battery is almost dead, and I'm giving the remaining energy to the chickens in the coop; it's well insulated, and the infrared lamp will give them a little warmth. Then the light goes out, the kettle on the stove will make noise, generators hum outside, and my two cats and dog are lying near the stove. Everything will be fine. I hope there won't be any shelling tonight, and tomorrow there will be sun, and we'll figure out something to make everything better)

Now I have a separate power supply for the LifePo4 battery and I can charge it quickly in sunny weather. Today the power was turned on for a few hours and it became a little easier.

This morning, at -20°C, all the batteries were dead. Thank goodness it was sunny, and I was able to fully charge the batteries and heat the chicken coop. The new charger allows me to charge the 100A backup battery from the sun several times faster. Finally, after a few days, the power came back on (probably for a few hours). The grid voltage is 180V, so thanks to the charged batteries and the sun, I won't be putting a strain on the city grid. I tested the new secondary heat exchanger, and the results are excellent: the water is boiling hot on the first setting. I temporarily covered the battery with a cotton blanket; thank goodness I insulated this room and it's below ground level. It's also a good thing I placed the equipment here, not on the veranda, as advised. The house is warm thanks to the stove, but the dog still wants a blanket).

The stove upgrade is complete for now, and it's proven itself. I won't clutter this thread. This thread will only contain information about the stove. More information on surviving a blackout during the war will be posted here.

(This comment is based on my assumption that you find solar panels too inefficient in your circumstances, for whatever reasons, rather than that you have zero access to sunlight.)
Have you looked into _bifacial_ panels oriented vertically?  
It resists holding snow so snow maintenance is easier.  The panels catch a lot of light from the back of the panel and have a surprising amount of effectiveness and efficiency.
Vertical orientation means they reduce damage from heat so they increase the life of the panel.
They can be used as part of a fence or as a bit of a window screening for a little more privacy, added sun shade in the summer if oriented correctly for summer sun.
Have a white painted surface behind it to increase the amount of reflected light it receives.

Not meaning to offend by asking about this but using bifacial panels oriented vertically is a new thing.

You're absolutely right, vertical panels produce very good results in winter. We even have professional installers installing solar panels on walls and making fences out of them, since panel fencing is cheaper than fences made from other materials. Double-sided panels are especially good for individual structures when there's snow underneath them in winter. I upgraded my brush, and now it's 11.5 meters long, considering it's made of aluminum. I can use the gutter as a support point. It's very convenient for me to clean the roof. I have a video on my TikTok profile showing how convenient it is to remove snow with this brush. Unfortunately, I have a low-power 6.5 kW inverter, so I can't add more panels. If I did, I would have mounted them on the wall. But despite all this, the panels helped me survive the winter. I don't have a gasoline generator, and my neighbors use theirs 24/7, which is very expensive. Despite the fact that I have a cheap inverter, its advantage is that it can collect sunlight even in cloudy weather.There are also successful experiments that, after modernization, make it possible to obtain electricity in winter from panels placed on the north-facing sides of roofs.
