5KW home solar system with battery backup: the full configuration

The configuration in full

The array is 5.6KW of monocrystalline panels, made up of 16 pieces of 350W. The inverter is a 5000W unit working from a 96VDC battery side, and the maximum load is 5KW (7KVA). The battery bank is 8 pieces of 12V 200AH gel batteries. Daily generation is about 33.6KWH under the stated conditions.

Two cautions belong with those figures. First, they describe this configuration only; they are not a promise about any other system. Second, a configuration is only as good as its match to your house: your roof, your shading and your load list decide whether this set, a smaller set or a larger one is the right answer.

The load list behind the configuration

Behind the configuration sits a household load reference: the everyday appliances of a house are named with their draw, and the combined load is totalled at 4593W — inside the 5KW maximum. That load list is the real lesson of this page. A home system is not sized by the size of the house; it is sized by a list like this one, written for your own appliances, in your own pattern of use.

Notice what the method does to the conversation. Instead of asking whether a system is big enough in the abstract, you ask whether your list fits, which items you would drop during a long outage, and which items — refrigeration above all — are never dropped. If an appliance you depend on is not on your list, the configuration cannot be blamed for failing it later.

Who this configuration suits

This configuration suits a household that treats the grid as absent or unreliable and wants its essential and everyday loads carried by its own system, with the battery bank doing the work after sunset. It suits rather less a household with a stable grid that only wants to trim a bill: that household should start from the on-grid category and the comparison pages, where the configuration can be simpler.

It also suits buyers who want to see a complete, checkable example before commissioning their own. Every figure above can be checked line by line. When you ask for your own configuration, ask for the same completeness: array, inverter, battery bank and a load list, in one document.

Ordering this configuration

Before ordering, confirm the minimum order quantity and lead time for your configuration, and ask which certificate documents apply to the models named in it. Confirm also how the configuration will be packed and what the mounting hardware for your roof type consists of. Put the final configuration — not a summary of it — into the written order, so what arrives can be checked line by line against what was agreed.
