Yes but I figured if the Li packs were on fire, the inverter will be dead/shutdown anyway. Apparently you need lots of water to put out Li pack fires, no dry powder or C02. I was reading about it just the other day in relation to Li cell fires on airplanes and what they do to put them out. Interesting stuff.
A few years I was involved in doing the design approval of a very large hybrid power system on behalf of a government maritime administration (my bit was the noisy up and downy things and the system integration) and I was disappointed by just how little thought the battery manufacturers had given to fire control and how little interest they took in the matter. Their attitude amounted to trust us, we know what we are doing. The fortunate thing about that sector is you can say uh huh, you're going nowhere without my signature and as things stand the only document you will be getting will have "not approved" on it.
