Orion inverterand enphase battery

[Pipitty123]

Hi, l just purchased a house which has a solar system installed. It has 5kw capacity panels and a orion inverter, which l assume is a 4.8kw model, not sure. Couple of questions if l may, l have seen cheap enphase batteries for sale, ones that can connect to the grid. Capacity 1.5kw. 1. Can l hook it an enphase to my current inverter. The reason l am asking is beacause that is all l can afford. 2. Are enphase batteries any good. 3. If they are no good should l replace the inverter, if so, with what. 4. I am too old to get up on the roof to look at the panels to see what they are. Any advice appreciated.

What do you want the battery to do?

Im new to battery use, l thought they drew solar untl full, then the house used some and the rest went to the grid.

How does a battery work?

If you are on grid, a battery works by costing you a bunch of $$ and then it wears out, and makes the vendor happy when you buy again. Only in very rare cases, where electricity is very expensive, will a battery break even for it's expense.

And if you have a battery, you have to have a generator to keep it charged and happy, because the same storm that killed the grid power lines, is still cloudy and your PV is not generating anything. (unless you are a rare case that looses power for a week at a time, several months a year)

Just get a moderate sized generator and a Transfer Switch for it, and you can keep the beer cool in the fridge if the grid goes down.
