Hysolis Apollo 5K • Expansion Battery

Fast Delivery. Thank you Hysolis! Recieved in about a week, and was very simple to install. Thank you, Ed

Hysolis impressed again!. I have four Apollo units , w 8 expansion batteries that run my whole house AND charge my two teslas…. It’s now gotten dialed in, and is performing super well…

Excellent

No issues at all.

Expanse and batteries helps with idle watt consumption of inverter. I love the plug and play installation of this system. If we have consecutive days of cloudy weather, the idle consumption of the inverter adds up over the course of a week, draining the power reserve for basic house functions, so having expansion batteries is really helpful. I live in a pretty cloudy part of the country so having a two expansion batteries per Apollo 5K gets me through a week of cloudy weather. Next, I’m working on expanding the size of my solar panel array, to enable quicker recharging of the system

I bought 2 extension batteries as I have 2 Apollos. Am still in the process of testing and figuring out. Only 4 stars for now but am satisfied so far. May update rating later.

More juice!. My off grid needed a little more power and this did the trick. Adding the 2 expansion batteries was a great addition to my 4 Apollos. And 28 Hysolis solar panels !!

Good price battery.. No problem and easy to install

Outstanding. Support and communication has been fantastic

Apollo 5k. You need to include the tool to disconnect cables to/from solar panels. I don’t like unplugging everything to go into eco mode . I am still awaiting the app so I can control the unit from my i-phone

Great Supplement. I added the expansion battery for cases where the power outage may be long, and cloudy weather might be extended. The units fit well together. Beware the battery is very heavy, so heed the two-person lift warning. With my current load, the single unit would go town to about 78% overnight, but with the expansion battery, it now only goes down to about 90%. Installation was smooth, and of course it came with the necessary cable. I also added the set of wheels as with both units together, moving them would be very hard without wheels. I do plan on adding additional load to the unit in the future, but already I'm appreciating the ease of mind in case of a power outage. We had a 5 hour outage a few weeks ago, and it was so nice not having to rush right out to set up the gas generator! One suggestion to Hysolis would be to add some specific documentation to just the expansion battery. There's likely not a lot to say as connecting it was pretty simple, but some clarification on how the expansion affects the overall unit would be nice
