    Alain was knowledgeable, patient and thorough as he helped me update the firmware for the Fortress batteries in a remote off grid setting. I really appreciated him taking the time to make sure everything was working correctly.

    Wow!! What a dream to install! Fortress new 18.5kWh E-VAULT ROCKS!! it totally goes in easy, lots of room in the wiring compartment and it just “makes sense” intuitively. Heck, this one is backing up the whole (quite large) residence using two SolArk inverter’s. SolArk pairs brilliantly with Fortress. Their support line is very helpful and they actually answer the phone. They are priced competitively believe it or not (LFP this high quality is WORTH the investment when you analyze LCOE across it’s…
