Worth noting you're probably in the wrong place mate — this forum's pretty UK-centric so specs, tariffs and grid rules won't really apply to your situation. Canadian grid regs are a whole different world.
That said, the battery and BMS side of things is fairly universal, so happy to chip in on that bit.
For home storage you'll want to be thinking LiFePO4 — safer chemistry, longer cycle life than standard lithium. Brands like Fogstar won't ship to you obviously, but the underlying cell quality questions are the same wherever you buy.
A few things worth nailing down before anyone can give useful advice:
- What's your daily consumption? (kWh, not just appliances)
- Grid-tied or off-grid? Big difference in how you size everything
- Any net metering available in your province?
For BMS, Victron is genuinely worth the premium for home installs — their ecosystem plays nicely together and the monitoring via VRM is proper useful when something goes sideways. Available in Canada too.
My own experience is mostly shepherds hut and motorhome scale stuff, so residential sizing is a bit beyond my usual, but the fundamentals don't change much. Others here will have more to add on the inverter/charger side.
What province are you in? Might affect what makes sense.
