Heat Waves
Do extreme heat waves adversely affect the solar generator/panel's ability to charge? I have a couple of 1500x' with expansion batteries and Victron MPPTs. Although there was very clear skies during the heat wave (Western USA), the expansion tanks depleted 50-75% although usage remained constant (as preceding weeks).

Hi @rdvenegas,
Can you please share more details about the setup you are using including model and part numbers and a picture if possible so we can better help you?
I know for sure solar panels and batteries are adversely impacted by high heat. If you can keep everything but the solar in the shade it will help alot. Panels should have some room to breath on their back side instead of being mounted flush against a roof.

GZ Yeti 1500X<Expansion Link Module<1200Wh Yeti Expansion Tank (1)<Victron MPPT 100/30 <5xBoulder 100. All connected with GZ-sourced cabling. Nearly all purchased directly from GZ.
The 5 panels are mounted on the roof of a 10'x16' tough shed with 1.5" air gap between roof and panel. The solar generator and expansion tank are inside the shed which is insulated with R-13 between 3/8" plywood sheathing. There is a shade structure that shades the shed's west wall from the late afternoon sun. The solar generator and expansion tank are a 2-3 inches from the insulated south wall. The five Boulder 100 panels face due south.
As of today, the system has "fully" recharged. Three days after the week of 105+ degree days where the system charge fell behind despite clear and open sun exposure.
