Build your full OUPES system

Vendor-locked configuration — only components OUPES themselves sells as compatible. We don't suggest cross-brand mixes that the manufacturer doesn't bless.

Why we don't suggest cross-brand mixing: connecting an OUPES battery to a different-brand unit isn't supported by either manufacturer's warranty, and the BMS protocols don't speak to each other. We only configure within a single brand's blessed ecosystem. If you want to mix brands, that's an intentional DIY choice — and you'll want a different tool than this one.

How the validator decides — wiring math reference
Voltage in series: Voc adds across panels. 3× 57.6V = 172.8V — exceeds 165V High PV ceiling. INVALID.
Voltage in parallel: Voc stays at single-panel level. 2× 57.6V parallel = 57.6V — under 60V Low PV ceiling. VALID at warm temps; cold-Voc may push over.
Cold-Voc derate: we apply panel cold-Voc temperature coefficient × ΔT below STC (25°C). Below freezing, Voc rises by ~10% — this is what trips the WARNING / INVALID line for tight-margin configs.
Current in parallel: Imp adds. 4× 4.21A parallel = 16.84A, exceeds the 12.5A Low PV input cap. INVALID.
Wattage cap: total panel wattage shouldn't exceed the input's max-watt rating. Excess gets clipped by the MPPT — operation is safe but you lose peak yield.

RV note: The OUPES Mega 5 has a native TT-30R outlet — a standard 30A RV plugs in directly, no L14-30 adapter needed. For 50A RVs you'd add a TT-30 → 14-50 adapter (~$35) but you'll only get 120V on each leg, not split 240V.

Coming soon
Skip if: you'll use the OUPES Mega 5 with extension cords or unplug-and-plug into appliances directly. Add if: you want a hardwired path to a transfer-switched 120V subpanel covering specific circuits (furnace, lights, refrigerator).
