SunGold Power 400 Amp 48VDC Bus Bar with Cover | 1 Pair

The SunGold Power 400 Amp 48VDC Bus Bar with Cover Gives Large Battery Banks One Organized Connection Point

The SunGold Power 400 Amp 48VDC Bus Bar with Cover is sold as a pair, shown in red and black. Each bar is rated for 400A continuous current at up to 48V DC and gives you a central point to join batteries, inverters, charge controllers and other high-current DC components.

SunGold made it for larger battery banks, solar energy storage, RVs, marine use and off-grid power systems. It suits anyone building a 48V system who wants the main positive and negative connections organized and covered.

SunGold Power 400 Amp 48VDC Bus Bar with Cover Features

400A Continuous Current

Each bar is rated for up to 400A continuous at a maximum operating voltage of DC 48V. That suits demanding battery and inverter circuits in high-power energy systems.

Nickel-Plated Brass Conductor

The bus is brass with nickel plating. SunGold chose it for dependable conductivity and corrosion resistance.

Six M8 Terminal Studs

Each bar has 6 x M8 (5/16") terminal studs, so several high-current cables can land on one bar for a flexible system layout.

Glass Fiber Reinforced Base and Cover

The base and cover are made of glass fiber reinforced nylon. The cover helps protect exposed connections and keeps the wiring organized.

Red and Black Pair

One red and one black unit make it easy to keep the positive and negative sides of your system apart.

Real-World Applications

Large battery banks. Connect several batteries at one point before the inverter.

Solar energy storage. Bring together batteries, an inverter and charge controllers.

RVs and marine systems. Organize the high-current DC wiring in a vehicle or boat.

Off-grid power. Build a tidy DC distribution point for an off-grid power system.

Practical Comparison

SunGold Power 400 Amp Bus Bar Versus Stacking Lugs on Battery Terminals

Stacking several cable lugs on one battery post makes connections harder to check and service. A bus bar gives each cable its own stud.

SunGold Power 400 Amp Bus Bar Versus an Open Bus Bar

An uncovered bar leaves live studs exposed. This pair comes with covers that shield the connections once the wiring is done.

Buyer Guidance

Ratings and Fit

The maximum operating voltage is DC 48V, so this bus bar is not for higher-voltage battery banks or PV strings. Keep the current through each bar within 400A, and check that your cable lugs fit M8 (5/16") studs. SunGold does not list stud torque, mounting screw size or whether mounting hardware is included.

This May Be A Good Fit If

• You run a 48V battery system
• Your main DC current stays within 400A
• You need several cable connections on each side
• You want covered, color-coded bus bars

Common Questions

Is It One Bus Bar or Two?

Two. The listing is one pair, one red and one black, each with its own cover.

How Big Is Each Bus Bar?

Each unit measures 138 x 69 x 48mm, or 5.44 x 2.72 x 1.89 inches.

Which Lugs Does It Take?

The studs are M8 (5/16"). Use ring lugs sized for that stud and for your cable gauge.
