I played a few hours with the new power system, and in general it appeared to work as expected, but I didn't perform any specific/targeted tests on it, only kept an eye on how it works and if anything seems off.
A few specific issues I've noticed:
- Systems appear to charge the battery even when they are turned off. I don't think this is how it should work, since it means that all the panel slots effectively belong to Electrical, not to their respective systems. When a system is turned off or has component failures, it should not be able to send charge to the battery, and its charge should be reported as zero on the hab status screen.
- The Reoxygenator power use line is "stuck", it always reads as 50 even when turned off, and it's added to the total drain on top of the screen. However, it doesn't actually drain power when turned off, only the display shows it all the time.
- When Electrical is turned off, the charge side of the total charge/drain line should drop to 0, since there's no actual charge happening without Electrical. The systems do produce those units, but at that time, without Electrical, it's not charge as such.
- There was one time when the hab status display completely broke: most of the text disappeared, and a single line of text (the charge/drain line of the Heater) started to fill the screen first upwards fron where it normally is, then also down to the bottom, and after a few seconds the normal status text returned. It was during a storm, so I'm not sure if it was just some intended but very rare display corruption related to that, but didn't really look like it.
A few notes on balance and possible improvements/changes:
- The Reoxygenator could switch to the low power state when there's no water available for it (nothing to break down so that part of the system powers down).
- The water and oxygen production rate is way too high. Since systems are now running constantly, unlike before when they throttled down for the night, they are producing probably close to twice as much as before. Their base production rate should be lowered significantly to compensate for this.
- Power production vs. use feels a bit high currently (I got about 40% left morning to morning with all systems running and suit charged up), and in part because of that, and in part to make choices between what to turn off a bit more interesting, I think the power use of the three producing systems could be tweaked a little as follows:
Water Reclaimer: 60/45
The increase is not as significant as it looks, since the Heater is practically always in low power mode (and the Water Reclaimer is also likely to hit cap after a while and power down, in which case it can even be turned off if you want to save power), so while previously the "nominal" drain from these 3 systems was 50+50+40=140, it would be 60+50+35=145 with these values. I think this would be just enough added drain to make the power budget a bit tighter.
- Because of the offline systems still providing charge, I coouldn't get really good info on how the power holds up during a storm, but in may be necessary to raise the minimum panel efficiency from 15% to 20%. as changes in the panel efficiency now have a different impact on the power balance than they had with the percentage based implementation.
